IC2 Crashing the server on start - Error saving user config

  • Hi, I'm having an issue with IC2 on a 1.12.2 server I'm setting up. IC2 will crash the server on launch even if I launch with only IC2 in the mods folder. The server runs fine without IC2, but I've made a bunch of mod integration for IC2 and I would rather not remove IC2 from my modpack.

    I've tried running it with two versions of forge server, the one that I'm normally using (since it is an old modpack) and the latest, and no one fixed the issue.

    Crash log is annexed.
