MC-197666Softlock when attempting to validate datapack
I was trying to get custom biomes to work in a datapack I'm working on. I noticed that there was an error in the console, saying that there should be a name at the start of a list under the creature compound in the spawners compound in a custom biome's JSON file. I changed it such that the list went "minecraft:cow":[<the rest of the list], closed and reopened Minecraft, installed the datapack while creating a new world, pressed done to get it to validate the packs, and...freeze.
Here's what seems to be the important bit of the log:

Changed Summary:

Please attach the data pack in question.
Wait, nevermind. It's not a freeze, it's a softlock. The music still plays, but it neve progresses from the "Validating selected data packs..." screen. I'll edit this accordingly.
Alright, I've updated it now. I've also included relevent labels.
Please also attach the datapack in question.
