Hi ! Im new at making Modpacks for minecraft, also i had never used this forum before but i really cant seem to find a solution to my problem. I am creating a minecraft 1.12.2 heavy modpack (129 mods) it didnt had any problems, i changed some of the mods configs and everything worked fine, but the last time i added some final mods the game just didnt generate a world, it gets stuck on loading world for eternity, so the only way out is to manually kill the Java tasks on the Task Manager.
After that it just obviusly display a crash, after looking for myself i did multiple things like allocate 7G of RAM to the modpack profile on twitch, get rid of some unnecesary mods, change the config in some heavy world generation mods, disable some heavy features, etcc. But nothing so far helps, i cant get the modpack to generate a simple survival world (Im using Biomes o Plenty and Recurrent Complex as the most heavy generation mods). So is there anyone who knows how to solve this kind of issues ??? Or have any ideas ??? (Ive heard of pre generating worlds, but the only way i found was to use Pre-Generation Chunks mod, and that mod is uncompatible with some of the mods i want!)
Heres some of the mods that im currently using to create my modpack: (Just the ones i know are heavy out of the 129):
