So, I was experimenting in a random "mod" workspace and I tried to run it, so that I can create a world and see if the things I made worked. But it crashed! I only made a block, a biome and a dimension (if that could help). Can somebody please explain why this happened? Maybe 3 elements are so few, that will cause the run button not to function properly? Here is something else that may help:
