Can't generate a new world

I made a mod in Mcreator 2023.4 and updated it in 2024.1, and it seemed to work, but now I added a biome and when I try to generate a new world, the loading screen stays at 0%. I can wait 10 hours and it will still be on 0% . I didn't add anything that could cause trouble in that biome, it was just a regular desert, but with black sand instead of regular sand, and no cacties. Then, I tried deleting the biome and all the feature it contained, but then when I clicked on create new world, the game instantaneously crashed. The worst thing is that the Console didn't give me any information at all.
