"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"

Eh, there are a ton of exceptions in your stack trace that classes are missing. Are you sure you have stuff like the FabricAPI, fiber2cloth? Also, this is still serverside. Stop putting client mods into the server mods folder. In the newest build, it should be marked as a client mod, but even then it's really bad practice and will in the future cause more startup issues.
