Large Slideshows in LrC on Mac OS Big Sur Won't Load

My ancient Lightroom Classic (v.9) on my ancient MacBook Pro running Catalina 10.13.6 has no problem loading a slideshow containing 14,000 images. In less than a couple minutes, we can airplay a slideshow containing any number of images—and we have a lot!


On my new MacBook Pro running the latest Big Sur OS and the most recent LrC version 10.4, it takes more than 5 minutes for a small slideshow of slightly more than 500 images to load. A collection of 13,000+ takes a lifetime to cache, and then it chokes and dies. 


Every time I've tried to address this with Adobe directly—and this is the third time in two years!—there's been no solution or even acknowledgement that this problem exists. From a lay perspective, it feels like Adobe's ability to play nice with the Mac OS, as in, optimize caching and maximize processing speed, is completely lacking, from one update to the next.


The very same slideshow that doesn't play on my up-to-date and up-to-the task hardware/software configuration has no problem on my old hardware/software duo. I really hope you'll take this issue seriously and address it once and for all.
