Trying to run Homeworld Remastered

So I recently bought the Homeworld Remastered collection. I installed it, and played it through Steam.

The launcher loads fine but whenever I try to play any of the games (including classic) it doesn’t seem to run fully.

When I click to run a game, the launcher disappears, but nothing happens after that.
Can anyone help me with this?

EDIT: The launcher will run the first Homeworld classic perfectly fine. The others still do not work.
