Crash when I click New World

Whenever I click Create New World, the game shows "Saving world" for a moment then crashes. I don't know why this is happening, but it only just started after changing a sound in a custom biome. The console doesn't help, it's vague and full of junk.

Can somebody look through this chaos and decode what the heck this means? Thanks, you're my only hope.

Hey there! Sorry this is a bit late, but I was having the exact same problem. I tried rebuilding base files and regenerating code.

Fortunately, I found a solution:

When I checked my custom biome for any inconsistencies, I noticed that the custom tree had no blocks selected as its stem or branches. If you don't want one of those, select air. Deleting the block that was in there caused my game to crash whenever trying to load a world, even if the biome was in a different dimension.

I simply just changed the stem and branch blocks, rather than an empty area, which fixed it immediately. Remember to rebuild the mod after you make this change just to be sure.

I hope you see this and fix your error. Have a nice day!
