For 1.19.2, you cannot have unknown data in a data pack or else Minecraft will refuse to reload any loaded packs. This is classified as intended game behavior. As such, you will have to remove anything in this folder that doesn't relate to a mod you've installed.

For example, this pack supports Farmer's Delight on 1.19.2. If you do NOT have Farmer's Delight installed, you must remove the "farmersdelight" folder from this folder.

If you're playing vanilla, remove everything in this folder EXCEPT "minecraft".
