How to fix error error-fatal-app-exit in Windows 11

Solution Steps

1. 1 First, try restarting your PC. Press Windows key + I to open Settings, then go to System → Recovery and click 'Restart now' under Advanced startup. This clears temporary glitches that might cause the app to crash.
2. 2 If the error is specific to one application, try reinstalling it. Press Windows key + R, type 'appwiz.cpl', and press Enter. Find the application in the list, right-click it, and select 'Uninstall'. Then download the latest version from the official website and install it. This replaces any corrupted files.
3. 3 Check for Windows updates. Press Windows key + I, go to Windows Update, and click 'Check for updates'. Install any pending updates, as they often include fixes for app compatibility issues.
4. 4 If the error occurs with a game or graphics-intensive app, update your GPU driver. Press Windows key + X and select 'Device Manager'. Expand 'Display adapters', right-click your GPU, and select 'Update driver'. Choose 'Search automatically for drivers'. This ensures your hardware is compatible with the latest software.
5. 5 Run the application in compatibility mode. Right-click the application's shortcut, select 'Properties', go to the 'Compatibility' tab, and check 'Run this program in compatibility mode for'. Select 'Windows 10' from the dropdown. This can trick the app into thinking it's running on an older OS, which sometimes fixes crashes.
