The basic GUI that comes with the install of git: https://git-scm.com/download/win; was working fine in Windows 10 until one day I used it on desktop 3, and then I must have switched desktops and closed it or something because now when I launch the GUI it appears to open just fine but there's no active window on any desktop. The icon shows up on the task-bar and when I hover over it, it does show a perfectly fine preview of the running GUI, but when I click on it it doesn't go anywhere.

How can I get the window back?
