I know the mod says it might not work under linux, but I hope that submitting crash reports will help making it compatible for linux.

Also, not sure if it because I use linux or because I have litematica (it appears in the stacktrace, so I'm suspecting it might be a culprit) and other mods.

Anyway, here is the crash report :
crash-2023-12-27_22.48.31-client.txt

Litematica is not compatible with VulkanMod.

Is this something you will be working on?

Debug lines have been implemented in the main branch. So this should be fixed.
