Hey, here's a "So stupid, it's simple" solution.

I got a brand new Win10 system. WOFF ran very nicely, but would crash on about every third exit from a mission. I turned off videos. Still crashed.

I then went to Windows Media Player and, while installed, it wasn't configured (which amounted to selecting one of two options and clicking OK).

Crashes gone.

Probably not a solution for long time system owners. But if you are wondering why your brand new system is crashing, you might want to try this.
