Can't disable vanilla data pack by using commands.

Resolved
Invalid
1

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.

  1. You seem to be using a non-vanillla datapack. Try replicating the bug without the datapack.

Can be replicated without any other non-vanilla data packs.

What's the new crash report?

Please also ensure that the data pack is formatted correctly, 1.16 has changed a few things.

Uploaded a new crash report. And here aren't other data packs except for vanilla.

Confirmed, can be reproduced instantly.

In 20w22a 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.

The game will not allow the vanilla data pack to be disabled if your other data packs don't include required game information such as built-in block and item tags (for instance #piglin_loved for piglin behaviour) because the game would crash otherwise. Please make sure that all of these tags are implemented in your data packs. If they are, please attach a test data pack for showcasing the issue.

Your log shows that you have not defined tags required by vanilla. Because of this, this is not a valid report and intended behaviour.

But this datapack can be disabled in 24w09a.
