I tried to grab the log from after I joined the server, so hopefully this has enough info to be sort of helpful.

Versions:
emi-1.1.4+1.20.1+forge.jar
Forge-47.2.21

Log: https://pastebin.com/8b86dpeT

Let me know if you need me to check/find anything for more information and I can grab that.

There doesn't seem to actually be anything fatal on any EMI threads in this log. Some mod is breaking creative tabs which has a fallback and otherwise it seems like EMI gets to the point of baking search before an OpenGL render crash not caused by EMI on the render thread.
