Crash occurs within 1 seconds of observing any helicopter or airplane flying. I may be in the helicopter or simply observe it from a distance. A helicopter may be spooled up without causing the crash, but as soon as taking off the game crashes. Occasionally, when interacting with aquatic vehicles I also get a related crash, although I have not found a reliable way to reproduce this yet.
The crash occurs when using any audio device in single channel (mono) audio mode.
