Exception in server tick loop java.lang.NoClassDefFoundError

[jej]

I tried to start the forge server but it crashed. As I understand it, this happens because of the unseen world mod, but I can’t remove this mod because the world is already generated with it and won’t start without it. Is it possible to solve this? There my crashlog.

I tried it, but the mod was already involved in world generation and without it the world will not open. Is there then a way to give a second life to the world without this mod?

I don't think so - I have no idea
