Game Working in Unity But not as a Standalone

I tried to make a standalone that works fine in the Editor but breaks right down with the standalone. It has a problem loading prefabs. I have all the prefabs, and in fact every resource I am using in a resource folder but none of it is working.

 tiles[x,y] = (GameObject)Instantiate(Resources.LoadAssetAtPath("Assets/Resources/Tile_one.prefab",typeof(GameObject)),
                     
                                         new Vector3((transform.position.x+45)-10*y,
                                         transform.position.y+1,
                                         (transform.position.z+45)-x*10),
                     
                                         transform.rotation);

That is what i am using to load the Prefab.

But i get this error in the outputlog.txt
