why texture2d sprite rendering not showing in game

I create a texture2d from camera data then render it on a game object using sprite renderer. The image shows in the Scene view but does not display in game. Any ideas?

Heres the code

 Texture2D tex = new Texture2D(screenWidth, screenHeight, l.transparent ? TextureFormat.ARGB32 : TextureFormat.RGB24, false);
             tex.ReadPixels(new Rect(0, 0, screenWidth, screenHeight), 0, 0);
             tex.Apply();
 
             //
 
             float renWidth = Screen.width;
             float renHeight = Screen.height;
             
             // from texture
             //menu.gameMenu.mySpriteRenderer.sprite = UnityEngine.Sprite.Create(tex,
                                                                // new Rect(0,0,renWidth,renHeight), new Vector2(0.5f, 0.5f));
 
             // Encode texture into PNG
             byte[] bytes = tex.EncodeToPNG();
             DestroyImmediate(tex);
 
             //
 
             Texture2D texture = new Texture2D(2, 2);
             texture.LoadImage(bytes);
 
             menu.gameMenu.mySpriteRenderer.sprite = UnityEngine.Sprite.Create(texture, new Rect(0,0,renWidth,renHeight), new Vector2(0.5f, 0.5f));
