Game not responding when entering a custom biome

If you create a custom biome file in the worldgen folder of a datapack and make it so it's the only biome in a custom dimension, the game stops responding once you teleport to the dimension and the game output just spams: "Received invalid biome id: -1"

What i expected to happen was that i would be teleported to the custom biome but what happened was the game stopped responding.

Steps to reproduce:
1. Create a custom biome file in the worldgen folder
2. Make a custom dimension in which only this biome can spawn
3. Teleport to the dimension via the execute command
4. The game stops responding and the game output spams: "Received invalid biome id: -1"

The data pack is attached
