Game freezes/crashes from error: "java.lang.IllegalStateException: Requested chunk unavailable during world generation" while data pack is installed.

For some reason my data pack is causing the game to freeze/crash when loading certain chunks.

To recreate the error:

1. Create a new world with the seed set to: 8400069217514695303 and with the provided data pack installed.
2. Run this command (should teleport you to a sunflower plains):
