Why does Microsoft Flight Simulator 2024 keep crashing randomly, and how can I fix it?
Microsoft Flight Simulator 2024 usually crashes “randomly” because of one of four things: incompatible add-ons, graphics driver issues, unstable system settings, or corrupted sim data. The quickest fix is to test with add-ons disabled, update and stabilise drivers and Windows, clear cache, verify the installation, and then reintroduce changes one at a time.
Why Microsoft Flight Simulator 2024 crashes seemingly at random
Most crash-to-desktop problems in MSFS 2024 are not truly random. They often look random because the trigger only appears under a certain aircraft, airport, weather condition, memory load, or background software combination.
In practice, we see the same few causes again and again:
- Outdated or broken add-ons, especially aircraft, scenery, utilities, liveries, or older packages carried over from a previous sim setup.
- GPU driver problems, including bad updates, corrupted installs, or instability when the sim switches load sharply.
- System instability, such as CPU, GPU or RAM overclocks, undervolts, EXPO/XMP instability, or aggressive tuning that passes light tests but fails in MSFS.
- Corrupted cache or sim files, including a damaged rolling cache or incomplete package update.
- VRAM or memory pressure, which tends to show up at dense airports, in complex airliners, in VR, or after long sessions.
- Overlay and hook software, such as frame counters, RGB suites, recording tools, controller software, or anything that injects into the sim.
If your PC throws a full blue screen or reboots, that is usually not the simulator itself. That points more towards driver or hardware stability.
What usually causes the crash? Start with the pattern
Before changing ten things at once, look for a pattern. The trigger matters.
| When it crashes | Most likely cause | What to try first |
|---|---|---|
| During startup or loading | Broken add-on or corrupted package | Start with Community add-ons disabled and verify files |
| At a specific airport or with one aircraft | Bad scenery or aircraft package | Remove that add-on and test with default content |
| After 20 to 90 minutes | Memory, VRAM, cache, heat or system instability | Reduce settings, clear rolling cache, remove overclocks |
| Only in VR or at ultra settings | VRAM exhaustion or driver issue | Lower texture and traffic load, update or reinstall GPU driver |
| Only with online traffic, live weather or utilities running | External interaction or background conflict | Test offline with overlays and utilities closed |
How do I fix random crashes in Microsoft Flight Simulator 2024?
Work through these in order. Do not skip straight to a full reinstall unless the earlier checks fail. In most cases, the cause shows itself much sooner.
Disable all add-ons and test a clean launch.
Temporarily empty or rename your Community folder so the sim starts without third-party content. Then load a short flight in a default aircraft from a default airport. If the crashes stop, the sim itself is usually fine and one of your add-ons is the problem.
This is the single best first test. A lot of “random” CTDs come from one outdated package that only breaks under certain conditions.
Use Safe Mode if the sim offers it after a crash.
After an abnormal shutdown, MSFS may offer a safe startup with add-ons disabled. Take that option. It is the quickest way to separate core sim problems from third-party content.
Update Windows and your GPU driver.
Install current Windows updates, then update your graphics driver. If you already updated recently and the crashing started after that, a clean reinstall of the driver is often better than stacking versions on top of each other.
For CTDs with no error message, graphics drivers are a very common culprit.
Remove overclocks, undervolts and RAM tuning as a test.
Return CPU, GPU and RAM to known-stable settings. That includes aggressive undervolts and memory profiles if you suspect instability. MSFS is unusually good at exposing borderline instability that other games seem to tolerate.
If the sim becomes stable at stock settings, the crash was not really random at all. Your tuning was.
Turn off overlays and background hook software.
Close monitoring tools, recording overlays, RGB control suites, motherboard utilities, controller remappers, browser hardware acceleration tests, and similar extras. Anything that draws over the sim or injects into it is worth suspecting.
Leave only the essentials running and test again.
Clear or disable the rolling cache.
A corrupted rolling cache can cause loading problems, stutters, and occasional CTDs. In the sim’s data settings, delete the rolling cache and either recreate it or run briefly with it disabled to test.
If you have been troubleshooting for a while, this is a sensible reset step.
Verify or repair the installation.
Use your platform’s file verification or app repair option. Steam, Xbox app and Microsoft Store installs handle this slightly differently, but the goal is the same: check for missing or damaged files without guessing.
If you recently had an interrupted update, this matters a lot.
Reduce settings that hit VRAM and memory hardest.
Do not just lower everything blindly. Start with the settings that most often trigger crashes under load:
- Texture resolution
- Terrain and object detail
- AI and ground traffic
- Glass cockpit refresh or avionics-heavy options
- Ray tracing or extra rendering features, if available on your setup
If the sim crashes mostly at large handcrafted airports or in complex airliners, this step is especially important.
Test with a simple baseline flight.
Use a default aircraft, a small default airport, clear skies, and offline traffic if needed. If that works, increase complexity one variable at a time: then weather, then traffic, then your preferred aircraft, then scenery.
This isolates the trigger far faster than trying to fly your full usual setup every time.
Check free disk space and page file health.
Very low free space on the drive used by Windows or the simulator can make crashes more likely. So can a disabled or badly constrained page file on systems that need more memory headroom.
Long flights and dense scenery are where this tends to show.
Disconnect non-essential USB devices.
A faulty peripheral, duplicate controller input, or unstable driver can crash the sim or freeze it during loading. Test with only your main controls connected. Then add devices back gradually.
If the crashing began right after adding a new yoke, throttle, panel or driver package, take that seriously.
Reintroduce add-ons one group at a time.
Once the clean sim is stable, add content back in batches: aircraft first, then scenery, then utilities, then liveries. The moment the crash returns, the last batch is your suspect pool.
Do not dump the whole Community folder back in and hope for the best. That just hides the cause again.
Crashing with no error message versus freezing versus blue screen
Crash to desktop with no warning
This usually points to add-ons, drivers, or unstable graphics and memory behaviour. Start with the clean Community test, then driver and system stability checks.
Freeze, then desktop
This often leans towards memory pressure, cache corruption, or a specific asset loading problem. Large airports, photogrammetry-heavy areas and complex aircraft make this more likely.
Blue screen or full reboot
That is usually outside the sim. Think unstable RAM, power delivery, overheating, low-level driver faults, or a bad overclock.
If MSFS 2024 crashes only with one aircraft or airport
That is good news, because it narrows the field. If one aircraft always crashes and everything else is stable, treat it as an aircraft package problem first. The same goes for one scenery area or one handcrafted airport.
Remove that package, update it if an update exists, or test without any related liveries and sound or utility mods attached to it. Aircraft-specific crashes are very often caused by supporting packages rather than the aircraft itself.
Should you reinstall Microsoft Flight Simulator 2024?
Only after you have done the clean add-on test, driver cleanup, cache reset and file verification. A full reinstall takes time and often does not fix the real issue if the cause is an unstable system or a broken add-on that gets copied straight back in.
Reinstalling makes sense when:
- verification or repair fails repeatedly
- the install was interrupted or corrupted
- the sim crashes even when completely clean and freshly repaired
- you suspect the package location or permissions are damaged
The quickest reliable troubleshooting order
If you want the short version, this is the order we recommend:
- Disable Community add-ons
- Test a default aircraft at a default airport
- Update or clean-reinstall the GPU driver
- Remove overclocks and tuning
- Clear rolling cache
- Verify or repair sim files
- Lower VRAM-heavy settings
- Add content back one group at a time
That sequence solves the majority of random MSFS 2024 crashes because it tackles the most common causes first and avoids changing too many variables at once.
One last practical point
Keep a note of exactly when the crash happens: aircraft, airport, weather, add-ons loaded, and how long into the flight. That simple log often reveals the pattern faster than any tool. In MSFS, “random” usually turns into one very specific cause once you test methodically.
