I am failing to understand why is my screen black.
Try checking everything is in the same place. It’s very easy to end up with things in crazy locations, if you drag them into an empty viewport.
Looks like there is only one light in your scene, the point light. You also have a post process volume - what are the exposure settings in the post process volume? It’s possible that one point light is not bright enough to illuminate much of anything. If your post process volume exposure settings are set to manual, you won’t get the eye adaptation effect, which will automatically brighten your scene to specified levels. You may need to increase the point light intensity, or increase the exposure compensation, or both.
