Staff Properties Window not Showing on WIN32/64 with multiple Screens
The problem occurs when you are using more than one screen on Windows and having the most right screen set as main screen.
The Staff Properties window shows up somewhere out of range.
I could fix it by setting my most left screen as primary monitor, the window then show up on my most right monitor.
System
Microsoft Windows 7 (6.1 /7601) AMD64

Caused by the dialog remembering it's absolute screen coordinates (uses the top-left of the primary screen as anchor). The method for storing/retrieving this has been changed for the next version, preventing offscreen windows.
This was done in https://github.com/musescore/MuseScore/pull/2752
If you close and reopen the window, the press alt-space, press M and any arrow then move your mouse, the window will appear where your mouse is. If this doesn't work, you probably opened then closed the window, so just open the window and try again.
Nice find Mike!
If you often switch screen configurations you might consider installing (and assigning a shortcut to) the following plugin: https://musescore.org/en/project/resetdialogpositions
