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
