one or more of your main files did not compile properly (biome)

Hey, currently I'm making a minecraft cookie run mod. I'm making it for 1.16.5 forge, and it seems that when I attempt to add a biome and load the game I get this error.

I keep pressing "Regenerate code" but nothing works. How do I fix this?

(sorry if its really easy to solve, I haven't used mcreator in a while)
