Oh wow, yeah probably try with the more likely ones first, then, heh.
If it helps any I am running on 1.12.2 with better foliage and optifine as well, though of course settings within those will likely wildly vary.

I am running 2.0 with many mods as well, and it is not crashing; I'd recommend trying a binary search to figure out which mod is conflicting :S

Hmm binary search is not necessary if it's obviously conflicting with mods that screw up the rendering (like optifine, better foliage, particle culling etc. also my pack has 500+ mods that takes 10+ mins to launch and a binary search will take days if unlucky :/) I'll try with these mods later

UPDATE: This bug has been identfied, The bug is caused by Optifine. Tried both F5 and F6_pre1 on a clean modpack and both crashed the game. Uninstalling optifine resolves it.

How did you install optifine? (You should just throw it into the mods folder)

I installed it with a custom minecraft launcher but that shouldn't make any difference

Entity Culling checks the mods folder for a file with "OptiFine" in it's name and the ".jar" extension.

There's no such file in my mod folder. let me figure out how it's installed, hold on

It's installed into .minecraft\libraries
also the minecraft main folder is in .minecraft\versions\[version name] for me

Optifine has to be in the same folder as Entity Culling. Otherwise it won't work. (I might think about another way to detect optifine in the future but that has low priority since there is a way to play with both mods installed)

I think there should be other ways to look for a mod's jar file rather than searching for it in the mods folder.
I've seen other mods that once do it but fixed it, like https://www.curseforge.com/minecraft/mc-mods/dupefix-project
maybe you can try to read his code?

I updated the optifine detection in v2.0.1. Maybe that helps?

It's working, thanks!
