This has happened to me twice including this last crash in the last week.
I will start the game as the DX11 executable. Minimize it and let cloud fronts run for 30 minutes or so. When I maximize it to check on the clouds, I get a DX9 executable game error. Upon using task manager to close it down, it is aceshigh9.exe running. I just checked my two short cuts and they each target the correct executable. I just relaunched the DX11 shortcut and minimized the game to check task manager to see which executable is running, aceshigh11.exe is running. I will see if I can duplicate the crash upon maximizing the game from the task bar with cloud fronts running after 15-30 minutes.
The DX9 dmp file is attached from the previous crash on maximizing from the task bar.
