Game crashes as soon as I load into the server

[ItsVectr]

I am using as custom modpack called Attack of Reblacka. I am not sure what the issue is exactly but I can launch into the game just fine. As soon as I load into the server, it crashes. I don't even see the world or any errors. It just sends me back to the Launcher. Below is the log copied from the server console as well as the crash report file itself.

If I am being dumb and this is easy to fix, feel free to tell me how please. Technic Support doesn't answer reports so here I am.
