freezes on loading screen

[SpellRox]

First, sorry for my english, I'm dumb so I'm using google translator. I tried to install a modpack that had ars magica 2 but it always crashed in the ''initializing mods Phase 3. Post initialization - ars magica 2" phase. I thought it was the modpack, so I did a clean install with just ars magica 2 and it still crashed. I tried with 2 other modpacks that had ars magica 2 and none of them opened, they all crash on the load screen and do not generate a crash report. When removing the mod, all modpacks opened normally. I have 16gb of ram, I've tried to dedicate 4, 6, 8, 12gb. Versions of ars magica 2 that I tested were 1.4.0.010LE and 1.4.0.009. Talking to the modpack developer he couldn't tell me what could be happening. Thinking that curse might be installing an incorrect version of forge, I tried it in multiMC as well and the problem persists. Only log that was generated...
