Hello, I have an issue where on multiple blu-ray disks everything except the main title will save on some titles. I have searched this forum and google with no success in finding an answer.
I have performed the following troubleshooting steps:

Cleaning disks several times

Cleaned the drives heads

Ensuring computers power settings are correct

Reinstalled MakeMKV on both computers

Tried both drives on both computers

Set the retry setting to 25

I can't think of anything else to do. Both drives have been flashed via instructions from this forum. This issue does not happen on every disk but the last 10 I have tried are problematic.

What does MakeMKV have in the log it fails to save the main title?

The log is too big to put in the text box or attach.
Here is a link to the compressed file
or,the plain text file for those who are opposed to opening compressed files from random strangers.

Here are some interesting tidbits from the log:

Things get worse from there and eventually there's a 20,000 line debug statement… truly the most impressive I've ever seen from MakeMKV.

You've done pretty much all things we'd tell people to do when their optical drive is having trouble reading a disc. Since you're using a BU40N, I assume that's an external drive. Is it in an enclosure with its own power supply or is it powered by USB?

It is external. It is the archgon MD-8107-U3YC-UHD. It's USB-C and from the same computer I can power two 13 inch displays on a single port so I figured an external power source might not be needed.
I saw it was used on on this video

My wife has a huge library of movies, over 2000. I purchased a pretty beefy NAS to run plex. Maybe this drive does not fit the use case?
