Crash when trying to open certain inventories?

[spoorn]

Not exactly sure how to reproduce this. I think it happened when I tried to open the End Stone Smelter from Better End.

Minecraft 1.18.2
Fabric Loader 0.14.9
CreativeCore 2.6.12

Yeah this issue happens, when the gui is closed. Unfortunately I have dropped support for 1.18, but this issue has been fixed in 1.19. It happens if you press the inventory key to close the gui (if I remember it correctly it might also be the ESC key). Very sorry for the issue :|
