If an unlock method fails, such as if the TPM detects a change in boot components or a password is forgotten, you will need to use a recovery method to access your data. When you start your computer, BitLocker asks the TPM for the keys to the drive and unlocks it.

If your computer has the Trusted Platform Module (TPM) chip, BitLocker uses it to seal the keys that are used to unlock the encrypted operating system drive. But the system could not recognize this password. Hi, From your description, I understand that the recovery password is generated when setting up the Bitlocker.
