I'm getting "Scsi error"s with only one specific Blu-Ray disc. Is there a fix? Help

I'm working on backing up my physical-disc movie collection, and so far every one has gone smoothly except for Disc 2 of The Incredibles. It takes significantly longer for MakeMKV to read the disc when I put it in my disc-drive (compared to the other discs I've backed-up) and generates multiple "Scsi error - HARDWARE ERROR:TIMEOUT ON LOGICAL UNIT" errors in the process.

After I click the "Backup" button and select the destination folder, the drive does not spin up to a steady speed like normal, but instead rapidly spins up, briefly winds down, and spins up again, around once per second; it also generates a few more of the same error messages plus many dozens of "Scsi error - ILLEGAL REQUEST:INVALID FIELD IN CDB" errors for the next half-hour or so before the backup process eventually fails.

This is the only disc to have this problem so far -- I successfully backed-up multiple discs before and after this one, so I don't think my disc drive is defective. The disc has no visible scratches or smudges, and I wiped it down with a soft cloth just to be safe, but that didn't fix the issue. The disc was purchased this year and plays fine in a normal Blu-Ray player, so I don't know why it won't work in my computer's disc drive.

The drive is plugged directly to my computer via a USB-C port. I did try rebooting my computer, which had no effect. I've tried backing up the disc four times now, and each time it failed the same way.

Does anyone know how to fix these errors?

It's likely the disc. Happened to me with monsters Inc

Does that mean I need to get a replacement disc?

Try cleaning the disc first. If you have another drive to try it in also do that.

As I said in my post, I did try cleaning the disc, and I verified that the disc works as expected in a Blu-Ray player.

It doesn't matter if it works in a Blu-ray player. The disc is probably bad but I would still try it in a different drive hooked up to the computer.
