Installing games doesn't work

I can’t install games at all. Nothing works, restarted PC, reinstalled, updated windows, updated drivers, checked for enough space on the installation locations etc.

Gets stuck right after I press the “Install” button, I also tried to wait for 30 minutes but it was still stuck.

Any known fixes?

Windows 10
i5 6600K
16gb RAM

This is the same issue as the login issue I think. :slight_smile:
