The game crashes only with optifabric installed. It launches to the main menu just fine but whenever I try to launch a world it crashes. I tried it with multiple different shaders and without any shaders enabled and it crashed the same regardless. it also gives me an error in the top right saying Resource reload failed.

This is my mod list:
