Hello grady forrester,
I'm following up to ensure you were able to regain use of the computer. To summarize the technical constraints here, BitLocker 128-bit or 256-bit AES encryption is designed specifically to make data unrecoverable without the 48-digit key; there is no bypass, registry hack, or CMD command that can unlock the drive if you are not the original owner. The only viable solution to make the hardware functional again is to perform a clean installation by booting from an external USB drive created with the Windows Media Creation Tool. During the setup process, you must select "Custom: Install Windows only" and delete all existing drive partitions, effectively destroying the encrypted container and allowing a fresh OS to be installed on the unallocated space.
If the issue has been successfully resolved, please consider accepting the answer as it helps other people sharing the same question benefit too. Thank you!
