I installed the latest AMD Software: "Adrenalin Edition Revision Number Adrenalin 22.11.2 Recommended (WHQL)" from this link: https://drivers.amd.com/drivers/whql-amd-software-adrenalin-edition-22.11.2-win10-win11-dec8.exe while my computer was bitlocker encrypted. After the installer finished running it restarted my computer, but something went wrong as it caused my machine to be unbootable. Start-up repair could not fix the problem because it was unable to recognize the filesystem on the drive. After struggling for an hour or so with the command line I finally managed to figure out that I had to decrypt my computer. Once I decrypted the drive Windows was once again able to recognize the filesystem as NTFS; I still was not able to boot, but I was able to launch startup repair and have it fix my boot sector.
Finally, I am back into Windows, without losing my data. I work for an IT department; for a normal user this would have rendered their computer completely unuseable. UNACCEPTABLE AMD. Clearly your driver installers need some more work to be fully compatible with Bitlocker!
Looks like you've got some work to do! You'd better get to it!
