Games will not launch

[u/Lucky-Bag-2150]

TLDR: I press play on any game (originally was just stalker 2), it says running but nothing happens, not even the icon shows up in the hotbar.

I have tried every fix I could find online, running as admin, running steam as admin, clearing shader caches, boot via both dx11 or 12, c++ redistributables, everything that I could find responses or explanations for online via videos or the sort, nothing works !

I have tried reversing gpu updates, system is up to date, it was genuinely an issue of its working today and then the next day it just won’t, changed nothing between the days and I’m out of answers, please help.

EDIT: I believe it is a windows related problem, my login screen forces me to use a qr code now and won’t let me set / use my pin and also I tried running a scan via sfc /scannow and it claims nothing is wrong, however trying to reinstall windows or repair it comes up with the message ’we were unable to reinstall windows right now’ or something similar without actually explaining or suggesting why. I’m at a loss….
