How to fix error error-unhandled-exception in Windows 11

Solution Steps

1. 1 Press Windows key + R to open the Run dialog. Type 'eventvwr' and press Enter. In the Event Viewer, go to Windows Logs → Application. Look for recent 'Error' events with source 'Application Error' or '.NET Runtime'. This shows which app crashed and the faulting module (like a .dll file). This helps identify the culprit.
2. 2 Press Windows key + I to open Settings. Go to Windows Update and click 'Check for updates'. Install all pending updates, then restart your PC. Updates often include fixes for bugs that cause unhandled exceptions.
3. 3 Press Windows key + X and select 'Device Manager'. Expand categories like Display adapters, Sound, and Network adapters. Right-click each device and select 'Update driver' → 'Search automatically'. Outdated or corrupt drivers are a common cause of crashes.
4. 4 Press Windows key + R, type 'cmd', then press Ctrl+Shift+Enter to run Command Prompt as administrator. Type 'sfc /scannow' and press Enter. This scans and repairs corrupted system files. Wait for it to finish (may take 15-20 minutes). If it finds issues, restart and run again.
5. 5 If SFC doesn't fix it, run DISM. In the same admin Command Prompt, type 'DISM /Online /Cleanup-Image /RestoreHealth' and press Enter. This repairs the Windows system image itself. It may take up to 30 minutes. After completion, restart and run SFC again.
6. 6 If the error occurs with a specific app, try reinstalling it. Go to Settings → Apps → Installed apps, find the app, click the three dots, and select 'Uninstall'. Then download the latest version from the official website and install it. This replaces any corrupted app files.
