This solution from PC Gamer worked for me:
Nothing happens when trying to start singleplayer or multiplayer
This seems to be a problem affecting mobile GPUs. We've been unable to test it yet, but MustacheEmperor on GTA 5 Reddit proposes this solution.
"Open device manager, go to display adapters, and disable your nvidia device so only the intel card is enabled. After launching the game re-enable the nvidia card quickly. The game will then work. Seems like there's a compatibility problem with mobile nvidia cards."
