Every startup, BitLocker checks that the boot environment is unchanged. One firmware update can be enough to fail that check.
Reference guide: https://www.salvagedata.com/blog/bitlocker-recovery-blue-screen
When the check fails, Windows asks for a 48-digit recovery key before it will start. Knowing where that key is stored is the first step in every fix.
Where recovery keys are usually saved:
→ A personal Microsoft account
→ A printed copy
→ A USB drive
→ Entra ID for work devices
→ Active Directory
Keep this guide handy for the next firmware or Windows update.
