Issue with Windows Defender on Windows 11

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?

    I had this problem on all machines updated from 19043.1151 to 22000.120.
    This command from elevated PowerShell fixed the problem for me, try it and report the results:

    Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

I was unable to get this to work using the reset command, but the following worked. 

 

I checked the output of the following command and it looked like Microsoft.SecHealthUI was installed for other users on the system, just not mine.  

Get-AppxPackage Microsoft.SecHealthUI -AllUsers


I didn't have success piping the output of the above command to add-appxpackage at first, but I found another post where people were talking about restoring all appx packages on a windows 10 system for a specific user account which was the key. 

I ran the following command to fix this issue

add-appxpackage -disabledevelopmentmode -register ((Get-AppxPackage Microsoft.SecHealthUI -allusers).InstallLocation + '\AppxManifest.xml')
