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

I have tried everything in this thread, and nothing works. I have used DISM repair, SFC scannow, restore and repair in the app settings....nothing. I simply have a blank screen when I go to Windows Security, and nothing shows up in the taskbar.

 

Little_Joe This is what I get when I try and run this.
