By the way thanks for all the help your giving me!

Did you test it with a new world?

 

If yes, then it may refer to Oh_The_Biomes_You'll_Go-forge

I don't know instead of bringing me to the title screen like it should it starts at the loading world screen and then i go to server menu and i press cancel and instead of bringing me to the title screen it try to load a world? -latest log https://drive.google.com/file/d/1LJjF5mr8FLu6c-fn1sVX4AEvMgqo7wXW/view?usp=sharing
