Whenever I create a world it loads fine during creation but after leaving and returning It shows the error "Errors in currently selected datapacks 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 to manually fix it". As well it will not let me click on "load in safe mod". Any help or idea what is causing this would be greatly appreciated.
