"This issue is caused by BlockRenderLayerMap from what I can tell by now..." "Solution is to switch rendering side to client. This is done by implementing ClientModInitializer and adding a client entrypoint to fabric.mod.json"

magneticflux- commented 3 years ago

This is not a conflict. Simple HUD utilities crashed on its own. My mod also had a separate crash:
