So I made this modpack with alot of mods and I am trying to make a server to go with it and the server control panel appears when I click it but then it crashes and I've been trying to understand what's wrong in the crash report but I can't understand some of this and I've googled a bunch of stuff. It's probably not that complicated but I just can't figure it out. The Crash Report: https://pastebin.com/HBxxwrGb
