windows version 20H2 (OS Build 19042.1052

While working on the computer I move from different desktops without any problem most of the time.  I have 6 desktops now and use each for a specific task such as a Spanish Desktop, a Business Desktop, a Picture and Video Desktop etc.  Twice now when I've been in my Picture Desktop and wanting to drag the screen back to the Home Page it didn't move.  I couldn't move the desktop in either direction and tried closing all programs and tried restarted Fences but there's no restart it just opens up the configuration window and that works fine but I'm only able to see the one Desktop.  In order to get it working properly I've had to completely restart my computer.
