The German BluRay disc of Knives Out won't work.

It says "COPY PROTECTION KEY EXCHANGE FAILURE".

I added the dump file.

Is there something I should do? I've been digitalizing my whole collection these past few months (almost 300 movies) and it worked flawlessly up until now. Fantastic program.

Dump files should be emailed to sqv@makemkv.com if you want anything done with them.

Key exchange failures are often caused by failure to read parts of a disk. Cleaning is the first step.
