Holy shit. This happened to me last week.
Turned off Safe Boot when going back over to Win on a dualboot after 6 months. Wanted to avoid updates nuking my dualboot option. (Edit: As was a Win issue 6 months ago)
...enter Bitlocker recovery for Every. Single. Logon.
Just need to do one thing that needs genuine Win11 fingerprint and then I'm doing a 22.1 fresh install.
