Windows 11's Windows Security App can't open.

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

Little_Joe you're going to have to use the powershell.exe as an Administrator from C:\Windows\System32\WindowsPowerShell\v1.0 to get it to work at this point.
