Hi! First step is to confirm whether your device is joined to a work/school account under Settings > Accounts > Access work or school and, if it is company-managed, share the full error code shown in the second screenshot with your IT team.
If this is your personal Windows 11 PC and you’re no longer using any organisation account, try fully disconnecting any old work/school account under Settings > Accounts > Access work or school, sign out and back in, and then remove and re-create the PIN (and other Windows Hello methods) from Settings > Accounts > Sign-in options.
