Ok so I just found this thread, and apparently, as the first time it has happened to me, if you select the launcher window, even if it's stiff invisible, using the Tab key you can select the launch button and it works. You can guide yourself with the small preview when hovering the mouse over the icon in the side bar. Maybe it helps.
