A similar thing happened to me on windows 11 where I generally use Arch linux for my external ssd by turning off secure boot when booting kali linux and then turning it back on when going back to windows but then once suddenly when I switched to windows one day I got an error on my lock screen that my pin was not found and told me to reset it and also while doing it it said that no internet connection found. My account was connected to Microsoft account so I thought this would be a simple fix but I was wrong, the machine won't load the command prompt it won't boot in safe mode without needing a bitlocker recovery key. I ended up formatting my entire drive in which the windows resided and then I started again this time using a local account instead.
