Hi, @Nisarg Patel

Thank you for posting in Microsoft Q&A forum.

Sometimes, BitLocker encrypted drive can be unlocked with correct password or BitLocker recovery key on another computer because you have reinstalled the OS.
Or you may try to use the tool iBoysoft Bitlocker Recovery to see if it helps.
