This was occurring when I quit via the Quit button in the Main Menu GUI. I also repro'd this using the "Quit" command in the console.
I found this on Linux, but this was repro'd on Mac and Windows by other testers.
Attaching logs for all three platforms and the backtrace while GDB was attached to the game on Linux. (Callstack field is from GDB)
Setup:
Repro:
Result:
Game hangs/freezes then crashes.
Expected:
Game exits gracefully.
Frequency:
100%
