You're going to need to flash your's drive's firmware to enable LibreDrive before MakeMKV can handle your UHD disk.

The drive needs to be flashed to support LibreDrive before it will rip 4K UHDs. Fortunately, since your drive is a BU40N it is fairly easy and straightforward to do. The Ultimate UHD Drives Flashing Guide has instructions and links to the SDFtool Flasher and the firmware needed. The guide recommends:

BU40N on any Firmware directly to > BU40N 1.03MK

Thank you for helping me.
I am a novice in computer science.
The flasher sdftool tool seems easy to use but I do not understand which steps to flash the firmware
and which bin file to choose.
