While adventuring to find Spruce Wood, I walked into a chunk/coordinate that instantly made my game crash.

What I expected to happen was...:
I would walk into the chunk/coordinate without any problems.

What actually happened was...:
I crashed upon walking into the chunk/coordinate, and continue to crash each time I try again and again.

Steps to Reproduce:
Any relevant information needed to reproduce it is right here, I hope.

(Side note: When exiting out of the game, being in that area crashes, and gives me this reason: The game crashed whilst exception ticking world
