Disc dump finishes before it starts

[AnonymousUser98]

I click "dump disc" and it immediately finishes, creating only a log file. I'm using Kali Linux.

redumper (build: b739)

I have confirmed that /dev/sg1 is the correct drive.
Here's the gdb log (with my username changed to "user"):

The disc I'm trying to dump is a CD-ROM, and the optical drive is ASUS brand (just like the log says).

Hi @AnonymousUser98 would you be able to run with this drive on a debug build of redumper to get a better debug output?
Here is a debug build (Linux only): https://github.com/Deterous/redumper/actions/runs/30864911660

Actually superg has just published a potential fix for this with build 740: https://github.com/superg/redumper/releases/tag/b740

Please replace the redumper executable and try again.

Seems like it worked fine with the debug build (the one you didn't post a minute ago). Here's the log:
