Your mods.toml config file is incorrect.

Oddly enough I dont see an error. Try moving the file and letting forge generate another one.

I deleted the file and i generated another one. It loaded minecraft good but when i load a world, it crashes with the same error. then another error comes up.

java.lang.IllegalArgumentException: Can not hotload overworld. This must be loaded at all times by main Server.
