Errors in currently selected datapacks prevented the world from loading

I tried adding tags to my mod, and when I ran the client, this appears whenever I want to create a world or play a previously made world.

Tag creation:
 

public class mzojPaintTags {
	
	public static class Items {
		
		//paint brushes
		public static final Tags.IOptionalNamedTag<Item> PAINT_BRUSHES = createTag("paint_brushes");
	
		//buckets
		public static final Tags.IOptionalNamedTag<Item> PAINT_BUCKETS = createTag("paint_buckets");
				
		private static Tags.IOptionalNamedTag<Item> createTag(String name) {
			return ItemTags.createOptional(new ResourceLocation(Main.MOD_ID, name));
		}
		
		private static Tags.IOptionalNamedTag<Item> createForgeTag(String name) {
			return ItemTags.createOptional(new ResourceLocation("forge", name));
		}
	}
	
}

Setting blocks to tag:
 

{
	"replace":false,
	"values": [
		"mzojPaint:red_paintbrush",
		"mzojPaint:white_paintbrush"
	]
}
