Static meshes not appearing on new Blank project

I’m helping a student troubleshoot. They have created a new Games >> Blank project with Starter Content [x] checked. Normally we’d expect to see the table and chairs, but instead the only things visible are the sky and gizmos.

I’ve looked at the usual suspects, like Visible, Actor Hidden In Game, but no luck. When they double click a static mesh asset, like the Table, they get a gray screen:

They cannot even drag in from Create >> Shapes >> Cube into the scene.

I told them to uninstall UE5, and then try re-downloading it. Is there anything else I should consider?
