So basically, I trying to create a "Smoke Bomb", and for that I made Item that throwing a smoke bomb projectile, and after smoke bomb projectile is hit block, it should create entity "smoke zone" but instead of that I got immediately crashed. I can't even make a renderer for this entity in mod class, it give an error, and I honestly don't know WHERE and WHY.

public class SmokeBombEntity extends ThrowableItemProjectile {
    public  SmokeBombEntity(EntityType<? extends ThrowableItemProjectile> pEntityType, Level pLevel) {

        super(pEntityType, pLevel);
    }
public  SmokeBombEntity(Level pLevel) {
        super(ModEntities.SMOKE_BOMB_PROJECTILE.get(), pLevel);
    }
public  SmokeBombEntity(Level pLevel, LivingEntity livingEntity) {
        super(ModEntities.SMOKE_BOMB_PROJECTILE.get(), livingEntity, pLevel);
    }
    @Override
    protected Item getDefaultItem() {
        return ModItems.SMOKE_BOMB.get();
    }

    @Override
    protected void onHitBlock(BlockHitResult pResult) {
        if(!this.level.isClientSide) {
            SmokeZoneEntity smokeZone = new SmokeZoneEntity(ModEntities.SMOKE_ZONE_ENTITY.get(), level);
            smokeZone.setPos(getBlockX(),getBlockY(),getBlockZ());
            this.level.addFreshEntity(smokeZone);
        }
        level.playSound((Player) null, getBlockX(), getBlockY(), getBlockZ(), SoundEvents.GLASS_BREAK, SoundSource.NEUTRAL, 0.5F, 0.4F);
        this.discard();
        super.onHitBlock(pResult);
    }
}

public class SmokeZoneEntity extends Entity {
    public SmokeZoneEntity(EntityType<?> pEntityType, Level pLevel) {
        super(pEntityType, pLevel);
        this.noPhysics = true;
    }
    public SmokeZoneEntity(Level pLevel, double pX, double pY, double pZ) {
        this(ModEntities.SMOKE_ZONE_ENTITY.get(), pLevel);
        this.setPos(pX, pY, pZ);
    }
    public  SmokeZoneEntity(Level pLevel) {
        super(ModEntities.SMOKE_ZONE_ENTITY.get(), pLevel);
    }



    protected void defineSynchedData() {}
    protected void readAdditionalSaveData(CompoundTag pCompound) {}
    protected void addAdditionalSaveData(CompoundTag pCompound) {

    }
    public Packet<?> getAddEntityPacket() {
        return new ClientboundAddEntityPacket(this);
    }
}

Also I can't render a smoke zone entity in a mod class, but smoke bomb projectile works completely fine

 @SubscribeEvent
        public static void onClientSetup(FMLClientSetupEvent event) {

            EntityRenderers.register(ModEntities.SMOKE_BOMB_PROJECTILE.get(), ThrownItemRenderer::new);
          //HERE AN ISSUE  EntityRenderers.register(ModEntities.SMOKE_ZONE_ENTITY.get(), EntityRenderer::new);

        }
    }
}

added code for context

So basically after spending sometime I fixed that by creating a new renderer for smoke zone.
