How to fix any Microsoft app (Microsoft store, Xbox app, calculator,...) not starting.

For almost 2 years any Microsoft app hasn't been able to be booted, every time I've tried fixing it nothing works. Any solution I found have not worked, I've tried using Windows PowerShell, Microsoft apps troubleshooter etc. But nothing seemed to have worked and when I go into the "apps" section in the settings and search for the Microsoft store its not there, but when i search microsoft store in the search bar it does show up but without an icon. Even after reinstalling the store it still doesnt start up. I've even reset my pc before but after a couple of days it just bugs out again.
