You have a sphere in your scene that is hidden in the viewport but is set to be renderable (in outliner). This object is blocking the sunlight so your scene is black

If you need the sphere to be rendered but still allow light to pass through it and not cast shadows you can turn these off in the sphere objects settings under the ‘Cycles Settings’ tab
