Descripiton
When using a datapack with custom worldgen settings and having a biome with a "minecraft:ore" feature and "minecraft:tag_match" predicate crashes the game upon creating a new world.

I included the datapack in attached files (extract_me.zip).
The datapack works as expected in 1.16.2 pre-release 1.

Notes

• The game chrashes whether you use your own or built-in block tags.
• If you use a non-existing block tag, the world generates without the feature.
• If you use the "minecraft:block_match" predicate type, the world generates with the feature.
