Windows 11's Windows Security App can't open.
Alright guys, just now I'm trying to disable the Windows defender but I found out that I can't even open the Windows Security App. Anyone knows what's going on? Any solution? I'm looking for help. 
Hello,Suggest try the following steps:
- Open PowerShell by using Administrator rights
- Copy and paste Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage to the PowerShell window and press enter
- Close the PowerShell and retry
