So I'm trying to learn how to make a custom biome. I found a few examples and tested them and they were perfectly fine. But when I created my own one and run the game with the selected biome, the game crashes. it doesn't close it self. it just doesn't respond to anything and a few seconds later the program not responding dialog pops up.
also when the game is trying to join the world the console is full of this log:
The log file, datapack, world is included in the attachments.
I'm not sure if this is a bug or not but someone told me when the game crashes it's always a bug.
