I tried to rip 4k Shrek and it told me:

Using LibreDrive mode (v01.0 id=AA7B8585D3C9)
Using direct disc access mode
Loaded content hash table, will verify integrity of M2TS files.
Saved AACS dump file as C:\Users\hanna/.MakeMKV/MKB20_v76_Shrek_9F6F.tgz
The volume key is unknown for this disc - video can't be decrypted
Failed to open disc

any ideas?

Have you tried downloading the latest KEYDB.cfg file, copying it into MakeMKV's data directory (i.e. where MakeMKV also writes its TGZ dump files) and restarting MakeMKV?

Email the dump file svq@makemkv.com.

Read the hashed keys section of the UHD FAQ.
