Invisible or missing window

[Hazelyn]

It was working fine at first, but now when it starts up, there is no visible window at all. I've tried every method I could consider incase it was off screen, but it just doesn't seem to exist. I have no idea what I did wrong, or what it did wrong.

The program opens, the icon will be on my taskbar, but it doesn't seem to be anywhere.

Tested with the newest build to see, but the icon pops up onto the bar, still no window at all. Hovering over the icon seems like there's no app or anything. I'm not really sure what it's doing.
