Do your two displays use a single graphics card/driver instance or do you have multiple graphics cards installed?
There is a single graphic card driving the displays.

But In all cases the two instances will share Sigil settings files, so perhaps one is trying to open up on top of or behind the second instance?
The second instance opens in front of the first edition.

The preview windows isn't open. Book browser, code window, ToC and validation results. I closed the book browser and Toc leaving the code window and toolbars open and still the same result.

Edit: disabled everything except the code window and the same result.

No error messages, just returns to the command prompt.

Just checked and removed the second display. The issue still happens when I open a second instance of Sigil.
