Bug Mod or Software

I can't start my mod, three days before this post everything was normal, now it keeps giving this error I don't know what's happening I already deleted the .gradle and my .mcreator and it won't, it works when I create a new one mod, so the error is in my mod? But what's wrong if I didn't move anything on it, I just changed a few things in the dimension. Please help me, here is the image of the error: http://prntscr.com/1ktle6d
