That worked.  First, I copied the original <file>.lyx to 
<file>-lyxformat-508.lyx, then ran 
$>/usr/share/lyx/lyx2lyx/lyx2lyx <file>-lyxformat-508.lyx -o <file>.lyx

That successfully converted the original to format 544, which the frontend was 
able to render.
Is it possible that there's a bug in the automagic process?
I'm running the installation from the rpm packages distributed for Fedora core 
35/36.
