It's possible it enumerated the wrong display. The game will always try to run on the "primary" display. If you want to run fullscreen, it might be better to keep the game in windowed mode, but choose a fullscreen resolution, this will give you a "borderless window" fullscreen resolution which other users have said solved their problems.
Let me know if you continue to have difficulties. We want you to be able to play the game the way you want to.
Weirdly when I open the settings tab in game it crashes out with the same exit code error. Here's the runlog.txt file contents again if that helps.
