Hello Anitha K, welcome to Microsoft Q&A forum.
I’m sorry to hear you’re going through this. Unfortunately, there is no way to bypass BitLocker. BitLocker is a security feature designed to protect your data, and when the system asks for a recovery key, it cannot continue without that key.
You can find detailed guidance here: Find your BitLocker recovery key – Microsoft Support.
Please note that even if you contact Microsoft Support, they will not be able to provide or recreate a lost recovery key. This is because the key is generated and stored locally or in your account when encryption is enabled, and Microsoft does not keep a copy for security reasons.
Go to https://aka.ms/myrecoverykey and check every Microsoft account you have ever used, as well as any work or school account if the device was managed. Also look for saved files, USB drives, or printed copies where the key might have been stored.
If the key cannot be found anywhere, the only option is to reset or reinstall Windows, which will erase all data on the drive.
I know this isn’t the answer you were hoping for, but security policies mean there’s no manual override. Wishing you success with the recovery process.
