I finally had some time to troubleshoot, and here is the issue.
I run MacBook Pro closed. Drive my 27 inch external monitor via display port. Primary external monitor run by StarTech USB dongle. If I unplug the USB-run monitor the Slideshow performs properly.
Displays have separate Spaces (on or off - no difference)
I tried playing an older slideshow and it worked. Didn’t try making a new one. Can you give more details on what you mean by “no longer functioning”?

All I can think of is to check the settings in the View menu for Secondary display. But you probably already did that.
