I do not have any 3rd party antivirus or anything of that manner downloaded or running. I have also tried repeating all the above steps but restarting in between. Furthermore, I do not have any VPN, DNS or Proxy installed/Running.

Rather, it just throws a lot of errors about the apps being on in the background and packages already existing. I have also tried repairing and resetting the Defender app through Settings > Apps > Advanced settings. Also, unrestricting and running the Get-AppxPackage -AllUsers does not work. Redownload the UI Elements does not help.

Same thing goes for DISM Scanhealth and Repair. I have tried doing sfc /scannow But the results does not show anything, and there are also no log files created. However, opening the app from Windows search shows some of the UI Elements, but no buttons or sliders. That i know because a resize results in red borders rather than a resize in UI elements. If i try to go in to Windows Defender from the settings app, the entire app seems to freeze. The behaviour of my app also seems to be different than is otherwise described online. The only thing i haven't tried is a reinstall, but i just installed all my apps and i really do not want to reinstall Windows. I've been scrolling for a good few hours trying to find solutions, but nothing has worked so far. It will not work no matter what i try to fix the problem. But i have been having an issue ever since i got Windows 11 for my Surface Pro 4, which i know is incompatible with Windows 11. This is my first post on here, so i am sorry if i maybe mess something up with the formatting or so.
