com.apple.DiskManagement error -69874

I have recently encountered the error "com.apple.DiskManagement error -69874" upon trying to conduct First Aid on a disk. Here's a picture of the full log:

Of course, some information is censored, but I had reasonably important info on that drive. It won't mount, either, and I really want it back.

The drive is USB 2.0 and my computer's USB ports are both 3.0.

I'd appreciate your help,
