The intention of the Bitlocker designers was to make it as resilient as possible to disk problems. Therefore the disk headers are duplicated on the disk. Some products claim being able to recover such disks, but they are very costly. I found only one product that is free as described below. Whether the disk can be recovered or not depends on the amount of destruction that was done.
The article How to Recover Files from Formatted Hard Drive (2023) claimssays that "EaseUS Data Recovery Wizard Free can recover files from formatted drive free on Windows and Mac computers".
Among the features is listed :
Unformat hard drive and repair the RAW drive (BitLocker encrypted drive)
Try this product. It's free and you have nothing to lose.
