UHD-AACS not recognized

[Feathered-Serpent]

Movie: Sonic the Hedgehog 2 (which features a normal BluRay and the UHD in the package)

The movie features Bus Encryption, but I also opened the disc in MakeMKV prior scanning to enable LibreDrive which bypasses the Bus Encryption for other tools then. Also no result without removing the Bus Encryption.

BluRay: MakeMKV: AACS v68 DVDfab: AACS protection (AACSLA) (MKBv68)

(Both ending at 50% because the scan of the duplicate folder is omitted)

Can you either upload the .inf file here or copy the contents? I'm wondering if it's laid out differently

[Feathered-Serpent]

As it is a binary file, I attached it.

MKB_RO.zip

Comparing it with the normal MKB_RO from the standard BluRay, it seems there are just some changed bytes, probably for AACS2.0: BluRay (last byte translates to dec 68):

UHD (last byte translates to dec 76):
