So basically I have had MCreator for a few days now, and I am running into this problem. When I try and open a gui I made when I am testing my mod, minecraft crashes. I have watched SEVERAL videos on how to make a custom gui/ crafting table (etc), but they are all outdated. I also couldn't find anything on any other 'discussion post' on the same issue or the mcreator wiki and knowledge database. Does anyone have a solution to this problem???
