Whenever I launch the game for the first time a day, it opens on the wrong monitor (Monitor 1 instead of 2) even though the settings in the menu show the main display is #2

I took a screenshot where I identified the monitors and you can see the game running on display 1 when according to the menu option it is open on display 2.

Note that the resolution also changes from 3840x2160 down to 1024x768.

I tried updating graphics card drivers but the problem persisted.
