This error happens every time when trying to open the world afterwards.

Removing the pack from the datapacks folder fixes the world.

In 1.14 this just locks up the game.

The crash is now different, I'm not sure what is actually the final fatal error, so I just paste them all:

Did nobody actually use my data pack to reproduce the issue? It didn't work the way it was. I thought datapacks always had to be unpacked to work, but apparently that's not the case, I just packed it wrongly.

Cannot reproduce in 20w14a. Please check if this is still an issue in 1.15.2 or the latest 1.16 snapshot.

I can still reproduce
