I don’t know enough about Windows 10/11, but aren’t they supposed to boot into a menu thet allows you to pick the last known good configuration before it evens boots to the gui?
It’s been a while since I had such a massive problem under Windows but the last time you could try to restore one of the last backups and usually that failed because Windows restore points are/were crap.
Apparently it’s because CrowdStrike installed their device driver as one that must start when Windows starts.

I’ve linked to the specific time where he explains that issue, but tbh the whole video is worth watching.
