A rotating problem in SDK

So I recently started working on an avatar storage world, and I wanted to create a decorative sphere that rotates above the world.

when compiled in unity, I can see my script that I added to the sphere object working. However when I build from the SDK, the sphere doesn’t turn.

Using SDK3, Unity 2018.4.20f1 (64-bit)

Script for Rotation:

public class Rotate : MonoBehaviour
{
void Update()
{
transform.Rotate(new Vector3(0f, 2f, 0f) * Time.deltaTime);
}
}
