Issue with entity renderer, game crashes when I try spawning custom entity.

I have tried to add a custom entity to my mod but when I run the mod I get this error:

No renderer registered for bigbadboybob2:caveman_entity

When I then try to spawn this entity main game crashes.

Here is my code for the renderer:

package lucas.MoeMobsMod.client.render;

import lucas.MoeMobsMod.MainMod;
import lucas.MoeMobsMod.client.models.CavemanModel;
import lucas.MoeMobsMod.entities.Caveman;
import net.minecraft.client.renderer.entity.EntityRenderer;
import net.minecraft.client.renderer.entity.EntityRendererManager;
import net.minecraft.client.renderer.entity.LivingRenderer;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.api.distmarker.OnlyIn;
import net.minecraftforge.fml.client.registry.IRenderFactory;


@OnlyIn(Dist.CLIENT)
public class CavemanEntityRender extends LivingRenderer<Caveman, CavemanModel> {
	public CavemanEntityRender(EntityRendererManager manager) {
		super(manager, new CavemanModel(), 0f);
	}

	@Override
	public ResourceLocation getEntityTexture(Caveman entity) {
		return MainMod.Location("textures/entity/caveman_entity.png");
	}
	
	public static class RenderFactory implements IRenderFactory<Caveman> {

		@Override
		public EntityRenderer<? super Caveman> createRenderFor(EntityRendererManager manager) {
			return new CavemanEntityRender(manager);
		}
		
	}

}

and here is my code for the render registry:

package lucas.MoeMobsMod.client.render;

import lucas.MoeMobsMod.lists.EntityList;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.api.distmarker.OnlyIn;
import net.minecraftforge.fml.client.registry.RenderingRegistry;

@OnlyIn(Dist.CLIENT)
public class CavemanEntityRenderRegistry {
	public static void registerEntityRenders() {
		RenderingRegistry.registerEntityRenderingHandler(EntityList.caveman_entity, new CavemanEntityRender.RenderFactory());
	}

}
