Hi, good day!
Please check the support article in the link below on How to find your BitLocker recovery key in Windows.
I apologize, but there isn't another way to get around BitLocker if you can't find the right recovery key or keep running into the same problem. In this situation, a Clean Installation of Windows via USB flash drive would be required. Please be aware that the BitLocker encryption will be deactivated during this operation, and your data will be lost.
I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Do keep me informed by clicking "Add comment" below.
