LG BU40N cant rip 4K disks after flashing

[Trolololman399]

Hey there,

I just got my Verbatim 43888 (with a LG BU40N inside) with 1.05 firmware, and used the SDFtool Flasher v1.3.6 to flash BU40N 1.03 from the "all you need firmware pack" (HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin).

After flashing, all the correct Info showed up in MakeMKV (see picture), and it even ripped a Blu Ray just fine.
But when I put a 4K in and tried to make a full disk backup, it failed during the decription phase (see picture).

The same behavior occured even when I tried to rip a known good (and not as recently released) 4K, The Batman (2022).

Is the drive defective?
Do I need to restore the firmware dump I made before flashing the drive?

I don't know what version of MakeMKV you are using but try v1.17.9.
