Windows client not playing video, displays picture and stops

[true911]

I'm new to Jellyfin and not a Linux expert.  I have an extensive Plex library and want to make the switch.  I installed Jellyfin server on a LMDE box and made a couple of mount points to try it out with the existing libraries (on a NAS).

I also installed the linux client on the linux box and things immediately worked as expected.  I then installed the v1.11.1 windows x64 client on a separate windows machine.  It seemed to communicate fine with the server, recognizing the IP, logging me in and displaying the movies in the libraries.  But when I press the play button on a displayed movie, it displays the full-screen image/thumbnail and then stops.  I cannot back up, no controls seem to work  I can only close the client window and start again.  

By comparison, the linux client also briefly shows the full-screen image before it launches the movie, so it seems to be part of the normal operation up to that point.

I wanted to include a log on this first message, but I searched and didn't see instructions on how to collect that.  If you need it I'm happy to comply.  However, the linux client working properly makes me think it is not a server issue.

I also removed the x64 and installed the x86 client, but that didn't work or load at all (on Win10 22H2).  I removed that and reinstalled the x64 and it continued to behave the same as above.

Thanks for your help.
