Edit: For people still experiencing crashes when pressing "Start Game" - delete your bin/ and garrysmod/bin/ folders and verify game cache integrity through Steam. Some 3rd party files/programs that may have been put into the game's folder by the player are causing issues, such as graphics modifications. Updating those files might also work.
