Data Pack Validation Problems

Recently, I've been having some problems regarding my mod's/forge datapack. Whenever I start a world, Minecraft tells me that data pack validation failed. Beginning the world with the default data pack results in none of my mod flowers/features/worldgen actually generating. My biomes still generate though. Trying to play past worlds also results in errors from currently selected datapacks preventing the world from loading. There are two options, safe mode and back to title screen. Pressing safe mode does nothing. I'd really like a solid answer to try and repair the errors to generate. I've recently deleted three of my custom biomes, all of them being locked, if that tells anything. My console logs are inserted down below.
