GC error whit canvas and LoadLevel

Here is scene what i was doing.. I just add Canvas and scroll view, nothing else :D

I have only one small script inside Main Camera

Script look like this:

 using UnityEngine;
 using System.Collections;
 
 public class ChangeLevel : MonoBehaviour {
 
     // Use this for initialization
     void Start () {
         Go("Test");
     }
     
     // Update is called once per frame
     void Update () {
     
     }
     public void Go(string LevelName){
         Application.LoadLevel (LevelName);
     }
 }
 

When i run scene my Unity shutdown, and i get CG error node on my desktop.. Is there some bug in Unity 5.2.1 or am i doing something "no no!" :D

If i close Canvas befor running script, everything go like it must, so there is no problem. I just want know, am i doing something wrong.
