One last question.
I downloaded and started the keydb helper.

It writes the keydb.cfg file to the folder
C:\Users\name\AppData\Roaming\aacs

The keydb website says to copy the keydb.cfg file to the following folder??

C:\Users\name\.MakeMKV
Which is correct?

More power was the solution.

What is the advantage of copying the keydb.cfg file into the .makekmkv folder?
There's a keydb-deu and a keydb-eng file. Should I use the keydb-eng file?

The problem was probably with my mini PC.
I reinstalled makemkv on my server with a 700W power supply and a USB-C to USB-C cable, and it reads the UHD without any problems.
I don't know what insufficient power has to do with the inability to decrypt it, though.

Thaank you, for the info.

Next try with Jurassic World Dominion
Can'T read the disc.
Der Volumenschlüssel für die DVD/Blu-ray ist unbekannt - das Video kann nicht entschlüsselt werden

next disc the same:
AACS-VID kann nicht gelesen werden - höchstwahrscheinlich wird das AACS-Hostzertifikat durch ...

Ok, I flashed it.
I just inserted a UHD disc, and it's reading it without any problems (so far) at 6x speed. That's very good.

What I find strange is that I can no longer select the "Save selected titles" function (3rd button).
And another question: If I check the boxes in the Integration settings ...

ok, what is with the button

include boot loader?

It is not activated by default.

yes, it is a new drive.
sdf tool 1.36 or 1.35?

and this one with MK from these pack
(All You Need Firmware Pack (MartyMcNuts))
DE_LG_BU40N_1.03_MK.bin

A drive is in the house, with no changes from me.

Nothing really helps,

I can't reflash the drive anymore. At least it still reads regular Blu-rays, so it's not completely dead yet.
Is it possible that the drive is having problems because it's not getting enough power via USB?
Then regular Blu-rays would probably have the same problems, right?

I ...

Do you mean this?
