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?

@SteveF01Did not work for me
I have tried PowerShell, old PowerShell, Windows Terminal PowerShell... but it doesn't work on my system.
I tried an on place reinstall, but nothing (before I could see wheels settings and it crashed only when I tried to add a new app, now it crashes as soon as I open settings section) and I have the Defender problem after a clean installation (it worked with previuos installation, which was an upgrade of a Windows 10 installation)...

@Asuka_Okami So I had the same problem since I upgrade from Windows 10 to 11, the problem is I have two users one is a normal user and another one as an Administrative user account, through the Administrative account I was able to access Windows Security, and then open the Windows Defender, what didn’t happen using the normal user, in the normal user it asks to install an App to open “windowsdefender”. so my conclusion is that Windows 11 limited Windows Security to be open only by Administrators’ accounts, but on Windows 10 I had the same users, and both I was able to open Windows Defender and make scans, now, through normal user account I only was able to open PowerShell as Administrator and execute scans using Windows Defender through the command line.

After trying your powershell command, I got the following error:
-AllUsers | Reset-AppxPackage Reset-AppxPackage : Package was not found. Windows cannot remove Microsoft.SecHealthUI_1000.22000.1.0_neutral__8wekyb3d8bbwe because the current user does not hav e that package installed.

What can I do now?

@fggIBthanks for sharing this! I just upgraded to Windows 11 (Feb 2022) and my security app was "missing" as well but this command fixed it immediately for me!

@SteveF01 I have been trying that command in the Admin' Command Prompt but always receive the error 'Get-AppxPackage' is not recognized as an internal or external command,
operable program or batch file.
Is there any way around this, as it appears that this error has never been ranked about within the forum?

Running Win11 - here's what worked for me.
Step 1.
Installed Powershell v7.2 from https://docs.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-windows?view=...
(I installed the MSI)
Step 2.
Ran Powershell as administrator and entered: Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
