Datapack doesnt show up during world creation

My datapack is in the installations datapack directory (so it should show up in the selection screen, but doesnt, when I manually put it in the correct directory and join the world it says:
Errors in currently selected data packs prevented the world from loading.
You can either try to load it with only the vanilla data pack ("safe mode"), or go back to the title screen and fix it manually
