The game crashes opening Quark config menu through Main Menu -> Mod -> Quark -> Config
The game would not crash opening the said menu from pause screen
This seems to have been caused by quark attempting to render entities of other mods, where some of which may fail when no loaded world is presented.

Try without optifine and I can even see MTJP lib in the call stack.

This is a project red bug.
