• Open Command Prompt as administrator (search for "cmd" and right-click "Run as administrator").
• Type sfc /scannow and press Enter.
• Wait for the scan to complete and restart your PC.
• If issues persist, run DISM /Online /Cleanup-Image /RestoreHealth and restart again.
• Create a new User Account to recheck the issue.
• If required, you need to reinstall Windows11.
