I'm new to Blender and last night I was working on a simple animation of cubes falling onto a plane. I saved the blender file and today when I opened it up and tried to render it, it refused to work. If I start a new project and render it, it works fine.
I've made sure that I have lighting, and I've messed with the output settings, but I can't get it to render. I was able to render the entire animation earlier today, but I closed out of Blender and when I reopened it, it renders blank.
This is how it looks when I change to render view in the viewport.
Then this is what the final rendering looks like.
Here's the .blend
