(Forge - 14.23.5.2860, 1.12.2) ^But I can't find any answers to it, I'm very new to making a Modpack and so far this is the only error, problem being I don't know how to fix it or probably any future errors either but it's between Mekanism(Not Community Edition) and UniversalTweaks, I was planning on making this into a server too but if I can't even get the client version working I don't know how I'm going to do that, so far I've tried checking the Config folder and the Configs within but couldn't find anything so I looked a the .class files and de-compiled them to see if those had any answers and that didn't have anything either.
