I assume the current userbase for MakeMKV on ARM64 is pretty small but I hope the following bug can still be fixed since recent changelogs also show ARM fixes.
For some reason (other people also confirmed it) UHD Blu-ray’s always error out in the beginning and want you to submit the dump for keys. Under Windows X86 the same Disc works just fine.
I also tried manually supplying a keydb.cfg but it still couldn’t decrypt.
