I'm trying to play with a few client-side mods right now but every time I try to load up the game, it crashes on startup with exit code -1 and the message "java.lang.IllegalStateException: Cannot get config value before config is loaded". I looked at the crash report: https://pastee.dev/p/dXprER4M#s=0 but can't seem to figure out what the issue is. If someone could help me with this, I'd really appreciate it. I just want to play with my mods...
