You don't have any bitlocker key uploaded to your account

Hello Vidhan Admin

If the recovery portal shows your device but no key, it means the BitLocker recovery key was never uploaded to your Microsoft account. The key is generated at the time BitLocker was enabled and is stored in one of a few possible locations: printed or written down, saved as a .txt file on a USB drive or another disk, stored in Active Directory/Azure AD if the device is domain-joined, or saved to a different Microsoft account if multiple were used. Check C:\Windows\System32\BitLockerRecoveryKey for any saved files, search your documents for files named BitLocker Recovery Key.txt, and verify if your organization’s IT department has escrowed the key in AD under the computer object. If none of these yield results, unfortunately there is no supported way to bypass BitLocker; without the recovery key the encrypted data cannot be accessed. At that point, the only option is to reset or reformat the drive, which will erase all data. If this is a corporate device, contact your IT administrator, as they may have the recovery key stored centrally.
