Hello,
I have since yesterday the same issue. MS-Support promised new installation, that failed because of bitlocker.
Actuallay the bitlocker pin is known and available. But trying to deactivate it via safe mode failed of the challanging phrase and pin-issue.
I found an workaraound on the net: (8) Windows 11 -Passwort vergessen FIX - YouTube
Works till choosing the partition, because of bitlocker :(
On another Win11 PC there are Options for choosing use password and renew the pin....
The issue popped up after an Update.
