进行渲染时游戏崩溃，在运行 net.minecraft.client.renderer.entity.EntityRendererManager.shouldRender 函数时，进行renders查询没有注册的渲染器

相关代码
进行相应渲染器注册后，列表中没有对应的渲染器注册结果：
ClientEventHandler

@Mod.EventBusSubscriber(bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT)
public class ClientEventHandler {
    @SubscribeEvent
    public static void onClientSetUpEvent(FMLClientSetupEvent event) {
        event.enqueueWork(() -> {
            RenderTypeLookup.setRenderLayer(BlockRegistry.glassJar.get(), RenderType.getTranslucent());
            ClientRegistry.bindTileEntityRenderer(TileEntityTypeRegistry.obsidianTERTileEntity.get(), ObsidianTER::new);
            RenderingRegistry.registerEntityRenderingHandler(EntityTypeRegistry.flyingSwordEntity.get(), FlyingSwordRender::new);
        });
    }
}

你这个EntityType注册了吗？请你补充一下这块的注册代码。

@Mod(Utils.MOD_ID)
public class Rocket {
    public Rocket() {
        IEventBus eventBus = FMLJavaModLoadingContext.get().getModEventBus();
        //eventBus.addListener(ClientEventHandler::onClientSetUpEvent);
        ItemRegistry.ITEMS.register(eventBus);
        BlockRegistry.BLOCKS.register(eventBus);
        TileEntityTypeRegistry.TILE_ENTITIES.register(eventBus);
        EntityTypeRegistry.ENTITY_TYPES.register(eventBus);
    }
}

public class EntityTypeRegistry {
    public static final DeferredRegister<EntityType<?>> ENTITY_TYPES = DeferredRegister.create(ForgeRegistries.ENTITIES, Utils.MOD_ID);
    public static final RegistryObject<EntityType<FlyingSwordEntity>> flyingSwordEntity = ENTITY_TYPES.register("flying_sword", () -> EntityType.Builder.create(FlyingSwordEntity::new, EntityClassification.MISC).size(3, 0.5F).build("flying_sword"));
}

@Mod.EventBusSubscriber(bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT)
public class ClientEventHandler {
    @SubscribeEvent
    public static void onClientSetUpEvent(FMLClientSetupEvent event) {
        event.enqueueWork(() -> {
            RenderTypeLookup.setRenderLayer(BlockRegistry.glassJar.get(), RenderType.getTranslucent());
            ClientRegistry.bindTileEntityRenderer(TileEntityTypeRegistry.obsidianTERTileEntity.get(), ObsidianTER::new);
            //RenderingRegistry.registerEntityRenderingHandler(EntityTypeRegistry.flyingSwordEntity.get(), FlyingSwordRender::new);
            Minecraft.getInstance().getRenderManager().register(EntityTypeRegistry.flyingSwordEntity.get(), new FlyingSwordRender(Minecraft.getInstance().getRenderManager()));
        });
    }
}

使用这种方式进行注册renderer，可以正常进入
