Solution Steps
- 1 Press Windows key + R, type 'sfc /scannow', and press Enter. This will scan and repair corrupted system files that might be causing the exception handling failure. Wait for it to complete (15-20 minutes).
- 2 After SFC, run DISM: Press Windows key + X, select 'Terminal (Admin)', type 'DISM /Online /Cleanup-Image /RestoreHealth', and press Enter. This fixes the system image, which SFC relies on. It may take up to 30 minutes.
- 3 Restart your PC. Press Windows key + X, select 'Shut down or sign out' → 'Restart'.
- 4 If the error occurs with a specific application, reinstall 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.
- 5 Check for Windows updates: Press Windows key + I, go to Windows Update, and click 'Check for updates'. Install any pending updates and restart.
