Hi
Do you still have access to your 48-digit recovery key?
You could try using
BitLocker Repair Tool to recover encrypted drive, check out option 2 in this method:
Recover
Damaged BitLocker Drive with BitLocker Repair Tool using Recovery Key
You will need to have an empty output volume (drive) of equal or larger size than the damaged BitLocker encrypted drive. The contents of the output volume will be completely deleted and overwritten by the decrypted contents of the damaged
BitLocker drive.
