I am launching MC Eternal from curseforge however, I have also tried on GDLauncher and MultiMC as well. I tried multiple modpacks but none will load either. Vanilla Minecraft will start up fine.
I have java 1.8.0.51 and 1.8.0.271 and allocated 10144mb of ram.
I also use these arguments: -XX:MaxNewSize=2000m -XX:SurvivorRatio=2 -XX:InitialSurvivorRatio=1 -XX:NewRatio=3
Please any help would be great, I've tried so many things and reinstalled and uninstalled many times but to no avail. The only error code I get when I force-quit the java binary in task manager is this:

ask in our discord, so we can give better support, this git is only for problems in the modpack
