for few hours I’m encountering issues with my Marvel Puzzle Quest game on Windows. When I open the game, game automatically closes and says "Marvel Puzzle Quest has stopped working. I already tried totally closing Steam, restarting computer, but it did not help.
I just launched the game without any problems. I’m on Steam too.
Try to verify the integrity of your installation. Open Steam, go to your library, highlight MPQ, right-click, pick Properties, go to the Local Files tab, and there’s an option to verify the game.
