Steam- Failed to start game (unknown error)

Steam- Failed to start game (unknown error) - Athletes Running on Track and Field Oval in Grayscale Photography

Every now and again Steam will decide to Show a unknown error popup when starting a game:

"Steam- Failed to start game (unknown error)"

The only way I can fix this issue is to restart Steam. This is troublesome because I am always in a voice chat when this occurs. I have no other programs running when this happens.

What could be the cause of this?
