Issue with Windows Defender on Windows 11

[Asuka_Okami]

I cannot open any of the settings on windows defender, when i try to it tells me to look for a compatible app in the Microsoft Store. Is this a bug or some other (fixable) issue?

@Francis_Powell  forgive me as I am not a computer technician. Although it's becoming more and more clear that I should need a degree in computer programming just to get this bloody thing to do it's job: compute. I digress.

Which PowerShell should I use? Windows PowerShell? Windows PowerShell (x86)? Windows PowerShell ISE? or Windows PowerShell ISE (x86)? oh and what the #$%^@#$^@ is PowerShell?

Reinstall using PowerShell Command
The problem is not new and has been reported by Windows 10 users as well when they upgraded from a feature update. The solution is relatively simple.

Open Windows Terminal and ensure it opens in PowerShell mode. Next, run the following commands

Set-ExecutionPolicy Unrestricted
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

I had Microsoft Security completely missing from my apps and features. This method worked perfectly. As a reminder you should run PowerShell as an admin or you might get a access denied message.
