I'm playing on Forge version 1.16.1, and only have 2 mods installed: Quark 1.16.1 and AutoRegLib 1.16.1. When I try to create a new world it gives me the pop-up "Errors in currently selected datapacks prevented world from loading. You can either try to load only with vanilla datapack ("safe mode") or go back to title screen and fix it manually. I can't choose safe mode, either. Is there a fix to this?
