While testing a datapack I'm creating, I get crashes from structure triggered advancements. I'm not entirely sure of the cause, I suspect it has something to do with structure detection in custom advancements. I have some advancements that are granted for visiting structures like monuments and temples. When I load this pack into a new world, I use /locate to find a structure, then while going there I usually get this crash. It crashes almost immediately again if I try to reload the world. The only ways I've found to stop crashing so far, are removing the datapack, or granting the structure advancements via command. I don't know if all structures have this problem, but I know desert temples for sure do (revoking the desert temple advancement near a desert temple immediately crashed the game). I attached my datapack in case its helpful in some way.

 To recreate crash:

1. Create a new world in an affected version
2. Load a datapack with advancements that detects structures (especially desert temples)
3. Find a desert temple
4. Hang out around it without getting advancement if necessary
5. Watch game crash
