Hello Waisea,
Yes, recovery is possible without formatting if a valid BitLocker recovery key or password is available. First check the user’s Microsoft account, Entra ID/Active Directory, USB backups, or the organization’s BitLocker recovery records for the 48-digit recovery key. If the key is found, the drive can be unlocked with manage-bde and the files copied without reformatting. If the drive has BitLocker metadata corruption, repair-bde may recover data to another disk, provided the required recovery credentials are available. If no BitLocker key/password or recovery material exists, there is no Microsoft-supported way to bypass BitLocker, so formatting should only be considered after all legitimate recovery sources have been exhausted.
I hope it's helpful to you :)
