makemkv hangs, makemkvcon at 100%

Hi all
MakeMKV v1.18.3 (new compiled)
Registered user.
Arch Linux up to date
I am trying to rip a BD, but the main MakeMKV window has "Scanning CD-ROM devices" at 100% and hangs there.
There is a process "makemkvcon" that eats 100% CPU time, which seems what the frontend is waiting for.
I can confirm that with 1.18.3 on Windows, with the same BD reader and BD disk, there are no issues.
Any ideas?

Is your sg kernel module loaded?
You can load it for the current session via modprobe:

In my experience, occasionally with some drives / discs, one could bump into this kind of hang issue if you inserted the disc *before* makemkv is started.

What do your system logs say? Or makemkv log?

Thanks everyone, and sorry for the late reply, we had holidays here.
> In my experience, occasionally with some drives / discs, one could bump into this kind of hang issue if you inserted the disc *before* makemkv is started.
When I first start makemkv, and then load the disc, it hangs indefinitely in the "Type: Loading ..." Label: Please wait" state
> What do your system logs say? Or makemkv log?
makemkv log shows nothing, just "MakeMKV v1.18.3 linux(x64-release) started"
System logs (journallog) gives nothing related to device loading etc.
> Is your sg kernel module loaded?
Yes it is:
I have doubted that my bluedisc support libraries are problematic, but I had no problem playing the disc using smplayer directly from the drive.
Thanks for any further suggestions!

Is your drive LibreDrive enabled? Upgrading my drive to LibreDrive made it work, before upgrading it was hanging. 1.18.3 on Debian 13.

Sounds like the same problem I am having. I just downgraded to 1.17 and it seems to work again. There are several other topics here about that. I think there might be a problem with 1.18 on Linux. Maybe even a MakeMKV-drive-compatibiliy issue? (I have no way to verify that though)

For the problem of 1.17.6/7+ not working with a non-LibreDrive (on Linux), the best workaround is probably the sdf_Stop setting. See e.g.
