Just tried to make one that's just forge without any mods and it still crashes. There are also no mods installed in my entire instances folder called "jukeboxfix".
I can't try right now but i doubt it would be one mod since i tried the classic "separate the mods folder into multiple folder and test each one individually", but every test i did crashed immediately :/
crash report - Pastebin.com/v5icCKie
I have tried to seartch online and repair both the modpack and my minecraft folder in the curseforge app but keep getting the errors for "fmlcore", "javafmllanguage", "lowcodelanguage", "mclanguage" & "Attempted to select two dependency jars from JarJar".
Please help
Edit: accidentally uploaded the wrong file to pastebin. now it should me the correct one.
