It sounds like your computer may have entered BitLocker recovery mode due to an incorrect PIN entry or a related issue. There are several scenarios that can lead to this situation, such as entering the wrong PIN too many times, changes to the boot configuration, or even hardware changes.
When you shut down your PC, if it restarts and prompts for a PIN, it could indicate that the system is not recognizing the correct PIN due to a lockout condition or other underlying issues. If you have a way to reset the password, that might help you regain access.
To troubleshoot further, consider checking the following:
- Ensure that no external devices are causing the boot sequence to change.
- Verify if any recent hardware changes or BIOS updates have been made.
- If you have access to the BitLocker recovery key, you can use it to unlock the drive.
If the problem persists, you may want to look into the BitLocker recovery process for further guidance.
