Game opened twice fine, but not after some video setting changes and some gameplay on the same run. 3rd+ stuck on black screen that I have to Win+P monitor/projector jiggle to reset the screen out of black and to then close out the game from desktop (to avoid restarting).

I'm wondering if there's some files I could delete to reset the video settings.

Followup:
Problem is intermittent but happens more often than not.

Workaround:
Do not use Fullscreen or Set to borderless

While in blackscreen press alt+tab.
Get out of black screen by tapping win+p 2x then Enter -- do this until you're out of black screen and set it right back to whatever you usually use if you want
Go to options and set back to Windowed or borderless and NOT Fullscreen
