Hi Mohammed,

Thanks for your post. You can try the following steps to resolve the issue:

1. Run the Windows Security Troubleshooter: Go to Settings > Update & Security > Troubleshoot. Find and run the Windows Security troubleshooter.
2. Repair Windows Security using DISM: Open Command Prompt as administrator and run the following commands: DISM.exe /Online /Cleanup-image /Restorehealth DISM.exe /Online /Cleanup-image /StartComponentCleanup
3. Re-register Windows Security apps: Open a Command Prompt as administrator and run the following commands: powershell -ExecutionPolicy Unrestricted Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
4. Reset Windows Security app: Go to Settings > Apps > Apps & features. Find Windows Security, and click Advanced options. Click Reset.

If none of these steps work, you may need to perform a clean install of Windows 11 to resolve the issue.

Best Regards,

Ian Xue
