Ok so basically I've started creating this add-on. I coded my first block into the game on  1.19's release date. Today at about 3:30 PM I started editing the add-on. Once finished I went to test it and got an error saying missing dependency. I looked through the add-on folders as well as the world settings and couldn't find any errors with either. I figured the world had just glitched, so I tried to create a new world. I went to activate the behavior pack and found out that it wasn't there. For whatever reason Minecraft would no longer detect the add-ons from the development_pack_folder.
