Are you using an endpoint management tool like Intune?
Is it possible the application control is being managed by a policy from your endpoint management system?
How to enable the use of an application from the system administrator in azure?
On a computer registered in a business domain, when the user tries to update some application (e.g. power bi) the computer informs him that "the application has been blocked by the system administrator". I am the system administrator and I do not know how to unlock the use of the Microsoft Store application.
