Windows 10: Windows 11 24H2 - Windows Security app blocked by your system administrator

I installed Windows 11 24H2 fresh install with all available updates yesterday and have had nothing but a nightmare experience. This is the latest issue I am facing and it's driving me crazy as I have found no fix that works anywhere online.I tried opening the Windows Security dashboard from the task tray and am shown this pop-up:I also get the same message when trying to open the Snipping Tool - for that, I tried the Reset and Repair options and it still doesn't work:There is no Group Policy blocking it from opening all settings are locally set to Disabled within these folders:The setting

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 ?

Just this week my PC has started blocking an app which I've been using recently quite regularly without issue.

I've followed all suggestions on various forums etc and still can not attain access to the App/Program.

Run as Administrator results in "This app had been blocked by your system administrator"

Hello, I'm configuring a new ASUS laptop, Windows 11 Pro, connected to AzureAD via the end user account, set up by my Global Admin account. When I'm logged in as the end user, "Run as Administrator" will not prompt to enter my admin credentials, instead I get "This app had been blocked by your system administrator" with Copy to Clipboard or Cancel options.

1. Device is registered with Intune, plan 1.
   
2. I am able to successfully "Run as Administrator" on other devices configured the exact same way, domain, intune plan.
   
3. I've double checked account status'. My account is listed as Administrator, while the user account is "Standard User".
   

Help would be greatly appreciated.
