Discussion Transparent Cutout shader not load from AssetBundle

I create Quad with VideoPlayer component. Video Render mode is set to material-override and renderer is this Quad. The material of Quad is with shader Transparent Cutout.
I make Prefab with this WholeObject. After that made AssetBundle from this Prefab.
Put it on my local server.

Then i use this script for loading that object:

public class BundleWebLoader : MonoBehaviour
{
public GameObject target;
private string bundleUrl = "http://localhost/assetbundles/myasset";

IEnumerator Start()
{
using (UnityWebRequest request = UnityWebRequestAssetBundle.GetAssetBundle(bundleUrl))
{
yield return request.SendWebRequest();
AssetBundle myLoadedAssetBundle = DownloadHandlerAssetBundle.GetContent(request);
var augmentation = myLoadedAssetBundle.LoadAsset<GameObject>("quad");

Instantiate(augmentation);
};
}
}

But i reseive only Pink Form of the Quad. With this error:
Renderer "Quad(Clone)", targeted by VideoPlayer, has no material with a texture property.
UnityEditor.VideoPlayerEditor:OnEnable ()

HOW CAN RESOLVE IT?
When i use Default-material for Quad(MeshRenderer) it works, but i want transparent video. Is it posible?

p.p. When the object is created is Pink. Without stop the Unity, i reselect same shader in the Quad and the object start with the video. Why not start directly when its created?
