MC-185302Can't disable vanilla data pack by using commands.
Before 1.15.2 this problem won't appear.
Before 20w21a, the game will crash when disabling the vanilla data pack by using commands. After the crash, join this world will make Minecraft crash again.
In 20w22a, the game won't crash but still can't disable the vanilla data pack. Here will be some words in chat says "Reload failed, keeping old data" and "Disabled data pack [vanilla]", but the vanilla data pack is still enabling. I think the new snapshot hasn't solved the problem but made the game not crash.
Warns in log (20w22a)
