Minecraft CurseForge

Can someone help me figure out why this modpack keeps crashing? Occasionally I get it to load, and everything is fine when I'm playing, but most of the time, the game crashes while loading and I can't even make it to the main menu. I don't know Java well enough to understand how to fix this issue, so I pasted the crash log below.

This is probably too late for you, but if anyone else finds this:

I had the same problem and so did my friend (using the latest version of Enigmatica 2: Expert, version 1.77).

The error that caused the Access Violation is this one (line 93f. in your crash log):

Current CompileTask:
C2: 173666 20365       4       pl.asie.foamfix.client.Deduplicator::deduplicate0 (459 bytes)

EDIT:

As the pack author suggested in my Enigmatica GitHub Issue, the correct way to fix this would be to tell the Twitch launcher to use the newest Java version.

Old Answer:

FoamFix seems to be an optimization mod that aims at reducing memory load during game start and ingame, so it's probably safe to remove, but I think I fixed it by setting the following settings in foamfix.cfg:

B:clearDuplicateModelRegistry=false
B:deduplicateModelBakers=false
B:deduplicateModels=false

This way only the "deduplication", which caused the crash, gets deactivated.

Any help on how to tell the Overwolf + CurseForge launcher to use a different Java version?
