LibGDX - problem with AssetLoader

can someone tell me where i make a mistake? i want to use AssetLoader to load textures but.... always have the same error. I thought that problem is with my game so I made new project but I still have error.

Couldn't load dependencies of asset: assets/badlogic.jpg

Here is my code:

public class TestApp extends ApplicationAdapter {
   SpriteBatch batch;
   Texture img;

   @Override
   public void create () {
      Assets.load();
      batch = new SpriteBatch();
      img = Assets.manager.get(Assets.image, Texture.class);
   }

   @Override
   public void render () {
      Gdx.gl.glClearColor(1, 0, 0, 1);
      Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
      batch.begin();
      batch.draw(img, 0, 0);
      batch.end();
   }

   @Override
   public void dispose () {
      batch.dispose();
      img.dispose();
   }
}

public class Assets {

    public static final AssetManager manager = new AssetManager();

    public static final String image = "assets/badlogic.jpg";

    public static void load(){
        manager.load(image, Texture.class);
        manager.finishLoading();
    }

    public static void dispose(){
        manager.dispose();
    }
}
