Bug Windows build opening on the wrong display

I have 2 monitors, but for some reason the built application is opening on the wrong display.
It isn't opening on the Windows defined main display but rather on my second display.

I moved it to the second display via windowed mode then set it back to full screen.
Restart the application and then it is fine. It saves the monitor last used.
Whenever I delete the registry key at HKCU\Software\{CompanyName}\{ProductName}
It reverts back to the wrong monitor. Meaning it is starting on the wrong monitor.

So if this is happening for any new user, it is quite annoying.
