Why is the map not loading in libGDX?

Good day.
Let's say I have a game designer friend who decided to send me a map created in the . He sent it to me in archive .
But I can't seem to load the map. The screen is blank.
Here is the code:

public class PlayScreen implements Screen {

    private MyGdxGame game;
    Texture texture;
    private OrthographicCamera gameCam;
    private Viewport gamePort;
    private Hud hud;
    private TmxMapLoader mapLoader; // for downloading tiles
    private TiledMap map;
    private OrthogonalTiledMapRenderer render;
    private World world;
    private Box2DDebugRenderer b2dr;
    private Player player;

    // light
    private PointLight light;
    private RayHandler rayHandlerh;


    public PlayScreen(MyGdxGame game) {
        this.game = game;
        texture = new Texture("badlogic.jpg");
        gameCam = new OrthographicCamera();
        gamePort = new FitViewport(
                MyGdxGame.V_WIDTH / MyGdxGame.PPM,
                MyGdxGame.V_HEIGHT / MyGdxGame.PPM, gameCam);
        hud = new Hud(game.batch);

        // load map
        mapLoader = new TmxMapLoader();
        map = mapLoader.load("maps/videns.tmx");
        render = new OrthogonalTiledMapRenderer(map, 1 / MyGdxGame.PPM);
        gameCam.position.set(
                gamePort.getWorldWidth() / 2,
                gamePort.getWorldHeight() / 2,
                2);

        // physics and polygon system
        world = new World(new Vector2(0, -10), true);
        b2dr = new Box2DDebugRenderer();

        BodyDef bdef = new BodyDef();
        PolygonShape shape = new PolygonShape();
        FixtureDef fdef = new FixtureDef();
        Body body;

        // create ground bodies/fixtures (polygon)
       /* for (MapObject obj :

            bdef.type = BodyDef.BodyType.StaticBody;
            bdef.position.set(
                    (rect.getX() + rect.getWidth() / 2) / MyGdxGame.PPM,
                    (rect.getY() + rect.getHeight() / 2) / MyGdxGame.PPM);
            body = world.createBody(bdef);

            shape.setAsBox(rect.getWidth() / 2 / MyGdxGame.PPM, rect.getHeight() / 2 / MyGdxGame.PPM);

well, they write to you that something is wrong with access to the array - going beyond the bounds, the index cannot be >= size, and you get size 3, you need to look at the code
