When I insert Fantastic Beasts 2 UHD into my external drive, I get this error: Failed to send host key (bus encryption) When I insert a different UHD into the same drive (I never had the problem with any other UHDs I own), it works fine (also shows "Disc wants bus encryption!" in log). I attached a log of both UHDs. The problematic UHD works in another drive. MakeMKV and any other software (which can remove UHD copy protection) were not active during the Windows session I tested. So I wonder why it fails for this specific UHD.
