Many people experience the bug in Grand Theft Auto V where the game freezes when they try to shoot out of a vehicle window during a mission.

Rockstar hasn’t been able to fix the bug so far, but there is a temporary workaround:

When you start the mission and get into the car, take out your phone and enter the Snapmatic app (you don’t necessarily need to take a picture), then close it and exit the phone. After that, you can shoot without the game freezing. The fix only works until you restart the game!
