Hello
Can you provide a screenshot of when the drive cannot be opened?
For Bitlocker-encrypted drives, if you know the Bitlocker key and do not want to lose the data in the drive, you can try the following solutions:
Check for Errors: You could try running a disk check for any errors related to hardware. Please note that while performing chkdsk on the hard drive, if any bad sectors are found, chkdsk tries to repair that sector. If any data is available then that data might be lost.
