I checked the file path and that seems to be fine as well. Not able to upload file structure photo as new users are only allowed to put one photo

        this.load.image('background', 'public/assets/BG.png');
        this.load.image('ground', 'public/assets/Tiles/Tile (2).png');

It looks like the error comes from these lines, you need to have those files in your local directory in that particular folder path.
