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 ?

How to Enable or Disable Microsoft Store Apps in Windows 10

I've returned from a two week vacation and no magic genie came to fix my problem. I've checked the policy setting mentioned by dalchina and it is 'not configured', so onto a different attempt. One thing that I discovered when reviewing the event log was that everytime I bring Windows up, five event id 1125 entries show, indicating some sort of group policy internal error.

OOOPS, I'l move over to the Windows 11 site. However, I am running Windows 11 Pro and I am using a standard administrator account - not the built-in one.

Thank you dalchina, I'll give this approach a try.
