Hey Game Programmer,
Do me a favor and create a new blank project with Starter Content. Create an empty (not default) level and place a stationary point light in the scene.
Drag the Shape_Sphere and the Floor_400x400 meshes into your scene so it looks like the image below. Build the Lighting and let me know your results.
Scene Set Up
If you are still experiencing issues after following the instructions let me know and I will continue to help you troubleshoot.
Thank you,
