So I am trying to open XCode (12.5 Beta 3) on my MacBook Pro (macOS Big Sur 11.2.3) but whenever I do nothing happens. Well, not exactly "nothing" because clicking the icon in the dock makes the top menu bar change to XCode, File, Edit, View, Find, Navigate... etc; and the little dot under the icon in the dock appears to show the program is running. But no window appears, I am just left looking at the wallpaper image. There used to be a window that popped up asking if I wanted to open a new project or an existing one. How do I get that back?
