If all else fails, submit the .tgz file generated by MakeMKV to svc@makemkv.com for analysis. Pro Tip: MakeMKV KEYDB.cfg Alternative
For 4K UHD discs, a keydb.cfg file alone is not always enough. Your Blu-ray drive must also be flashed with "LibreDrive" compatible firmware. If your drive cannot read the disc's data structure at a hardware level, MakeMKV won't even get the chance to test the keys in your configuration file. Ensure your drive is properly flashed and listed as "LibreDrive enabled" in the MakeMKV main window information panel. MakeMKV expects a hashed key format
Rename libmmbd64.dll to libaacs.dll (or use the 32-bit version if running a 32-bit VLC installation). On macOS / Linux:
