Item Display Error

[JCS-Mecabricks]

Description

I made a Block Entity in my minecraft mod that displays items. But When I updated from 1.21.8 to 1.21.9, it didn't display anymore. Is it because of the new methods I am using?
Here is my 1.21.8 version:
package github.jcsmecabricks.magicmod.block.entity.renderer;

import github.jcsmecabricks.magicmod.block.entity.custom.ExhibitStandBlockEntity;
import net.minecraft.client.MinecraftClient;
import net.minecraft.client.render.LightmapTextureManager;
import net.minecraft.client.render.OverlayTexture;
import net.minecraft.client.render.VertexConsumerProvider;
import net.minecraft.client.render.block.entity.BlockEntityRenderer;
import net.minecraft.client.render.block.entity.BlockEntityRendererFactory;
import net.minecraft.client.render.item.ItemRenderer;
import net.minecraft.client.util.math.MatrixStack;
import net.minecraft.item.ItemDisplayContext;
import net.minecraft.item.ItemStack;
import net.minecraft.util.math.BlockPos;
import net.minecraft.util.math.RotationAxis;
import net.minecraft.util.math.Vec3d;
import net.minecraft.world.LightType;
import net.minecraft.world.World;

public class ExhibitStandBlockEntityRenderer implements BlockEntityRenderer {
public ExhibitStandBlockEntityRenderer(BlockEntityRendererFactory.Context context) {

}
@Override
public void render(ExhibitStandBlockEntity entity, float tickDelta, MatrixStack matrices,
                   VertexConsumerProvider vertexConsumers, int light, int overlay, Vec3d cameraPos) {
    ItemRenderer itemRenderer = MinecraftClient.getInstance().getItemRenderer();
    ItemStack stack = entity.getStack(0);

    matrices.push();
    matrices.translate(0.5f, 1.15f, 0.5f);
    matrices.scale(0.5f, 0.5f, 0.5f);
    matrices.multiply(RotationAxis.POSITIVE_Y.rotationDegrees(entity.getRenderingRotation()));

    itemRenderer.renderItem(stack, ItemDisplayContext.GUI, getLightLevel(entity.getWorld(),
            entity.getPos()), OverlayTexture.DEFAULT_UV, matrices, vertexConsumers, entity.getWorld(), 1);
    matrices.pop();
}

private int getLightLevel(World world, BlockPos pos) {
    int bLight = world.getLightLevel(LightType.BLOCK, pos);
    int sLight = world.getLightLevel(LightType.SKY, pos);
    return LightmapTextureManager.pack(bLight, sLight);
}

}

And here is my 1.21.9 version:
package github.jcsmecabricks.magicmod.block.entity.renderer;

import github.jcsmecabricks.magicmod.block.entity.custom.ExhibitStandBlockEntity;

import net.minecraft.client.render.VertexConsumerProvider;
import net.minecraft.client.render.block.entity.BlockEntityRenderer;
import net.minecraft.client.render.block.entity.BlockEntityRendererFactory;
import net.minecraft.client.render.command.ModelCommandRenderer;
import net.minecraft.client.render.command.OrderedRenderCommandQueue;
import net.minecraft.client.render.item.HeldItemRenderer;
import net.minecraft.client.render.item.ItemRenderer;
import net.minecraft.client.render.state.CameraRenderState;
import net.minecraft.client.util.math.MatrixStack;
import net.minecraft.item.ItemDisplayContext;
import net.minecraft.item.ItemStack;
import net.minecraft.util.math.BlockPos;
import net.minecraft.util.math.RotationAxis;
import net.minecraft.util.math.Vec3d;
import net.minecraft.world.LightType;
import net.minecraft.world.World;
import org.jetbrains.annotations.Nullable;

public class ExhibitStandBlockEntityRenderer implements BlockEntityRenderer<ExhibitStandBlockEntity, ExhibitStandBlockRenderState> {
public ExhibitStandBlockEntityRenderer(BlockEntityRendererFactory.Context context) {

}

private int getLightLevel(World world, BlockPos pos) {
    int bLight = world.getLightLevel(LightType.BLOCK, pos);
    int sLight = world.getLightLevel(LightType.SKY, pos);
    return LightmapTextureManager.pack(bLight, sLight);
}

@Override
public ExhibitStandBlockRenderState createRenderState() {
    return new ExhibitStandBlockRenderState();
}

@Override
public void updateRenderState(ExhibitStandBlockEntity blockEntity, ExhibitStandBlockRenderState state, float tickProgress, Vec3d cameraPos, @Nullable ModelCommandRenderer.CrumblingOverlayCommand crumblingOverlay) {
    state.itemStack = blockEntity.getStack(0);
    state.renderingRotation = blockEntity.getRenderingRotation();
    state.pos = blockEntity.getPos();
}

@Override
public void render(ExhibitStandBlockRenderState state, MatrixStack matrices, OrderedRenderCommandQueue queue, CameraRenderState cameraState) {
    ItemStack stack = state.itemStack;
    if (stack == null || stack.isEmpty()) return;

    matrices.push();
    matrices.translate(0.5f, 1.15f, 0.5f);
    matrices.scale(0.5f, 0.5f, 0.5f);
    matrices.multiply(RotationAxis.POSITIVE_Y.rotationDegrees(state.getRenderingRotation()));

    HeldItemRenderer itemRenderer = MinecraftClient.getInstance().getEntityRenderDispatcher().getHeldItemRenderer();

    itemRenderer.renderItem(
            MinecraftClient.getInstance().player,
            stack,
            ItemDisplayContext.GUI,
            matrices,
            queue,
            getLightLevel(state.getWorld(), state.pos)
    );

    matrices.pop();
}

}
