Windows 10: app blocked by system administrator

The message app blocked by system administrator appears when I try to open MS Sec Ctr, and nothing happens when I click to open the Action ctr, start menu, or right click on taskbar icons to see the pop up context menu. And the clipboard doesn't work. I can't type in the search box on the taskbar. None of the searched solutions apply or work. I ran into this issue with another computer and it turned out that an update had not completed. I ran Win Update over and over to get all up to date. I ran sfc /scannow and followed with the 3 DISM.I am running win 10 22H2

This App has been blocked by your system administrator

On one of my 3 Windows 11 systems, I continue to be unable to run any of the Microsoft Store apps such as notepad, scan, calc, etc., including the Store app itself and instead get the following message - "This App has been blocked by your system administrator". I've spent many hours and visited many websites in an attempt to diagnose and resolve this problem - with no luck ! I've tried many suggestions posted on various websites with no positive results. I've uninstalled all of the Microsoft Store Apps and reinstalled them and still get the same message. Is there a comprehensive list of flags, settings (registry, for example), file properties, security policies, etc. listed anywhere that, if set, would cause this message to be issued, resulting in failure to start any of the aforementioned Store apps. I want to avoid reinstalling Windows from scratch - some not-so-obvious setting/policy is not allowing these apps from running. BTW, I am running Windows 11 21H2 (OS Build 22000.739). Any help would be appreciated. One last idea - are there any tracing capabilities that would log/trace the path from clicking on the app through to the point of failure ?

 

app blocked by system administrator

I just downloaded a game via the xbox app.

But whenever I try to run it, I get an error message saying "blocked by system administrator".

This is my computer, no one else uses it, there shouldn't be a 'system administrator'.

If anyone can help, that would be greatly appreciated.
