When creating and/or loading a world, I get a datapack error, but only with this mod installed. I have over 200+ and all work fine without this one turned on.

I have attached the debug.log file to this post.

I just ran all the mods datapack json files through a JSON validator. They all checked out.
Also tested with the mods datapack files removed, and that did load the world, but there were no recopies, etc. due to not having an accosted data pack "installed."
