Lightroom Classic 9.4 Slideshow module makes preview each time play button is used

Imac Mojave 10.4

How do I keep the slideshow from running the preview module every time I use “play” when there have been no changes in the slideshow whatsoever.  I am in manual mode and start and stop the slideshow.  This is becoming an issue as I am presenting a talk where I will be sharing images via zoom with another presenter.  My images are in LR Clasic slideshow.  When I relinquish my share for the other presenter to talk/share his computer, and then the share comes back to me.   Anytime I stop the slideshow with escape and then restart (no changes have been made), Lightroom rebuilds the previews.   This did not occur in earlier versions of Lightroom.   Is there a setting where I can prevent this.  It is time consuming and boring for my audience to watch a very slow build of the previews before the slideshow can begin.  Thank you.

Do you know of any setting that will keep lightroom from doing this?

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Past that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

Not a slideshow person, but I suspect you need to export it, to watch without it making new previews, then you watch the export.
