i've been trying to stitch up together a modpack together with changed mod, a rather large one, around 270 mods

i've noticed that the modpack never loads up, it stays at basically 100% and never finishes to load

on the logs the last thing happening seems to be Starting latex cover generation for 9680 blocks

when i get to that log my cpu spikes to 100% and ram usage gets to 100% as well

here is the latest.log (do note that i killed mc process forcefully from the task manager as my whole computer locks up)
