Crashes when trying to create a world it was in mod list and once removed it started to work again idk what happened but hopefully u can patch it soon

I would need to know:

• What mod version
• What loader (Forge / Fabric)
• If it crashed, provide a crash log.

To have any idea what is the issue for you.

Unfortunately I do not have psychic powers, and I cannot magically tell what is wrong with your setup. As Cyanide is meant to improve error reporting and detection capabilities and those capabilities don't mean squat if you just blindly ignore them.

I've replicated the crash.

Occurs using 4.0.0 of the mod with Quilt and its Biome API.

There is no Cyanide developed for, or tested against Quilt, at present, and you're on your own if you want to get that to work.
