Professional Print & Layout has stopped opening files

Their support webpage is full of broken links.  I have what should be a simple question: Why has Professional Print & Layout stopped opening files?

PRO-300, Windows 11, WiFi.  Until last week, Professional Print & Layout would accept drag & drop of JPGs and print just fine.  Now it shows the checkerboard pattern after the drag.  File->Open behaves the same way.  I upgraded to Windows 11 several weeks ago, but it worked after the upgrade. This is v1.3.0.

Suddenly drag and drop works.  File Open still does not, but I have a solution!

That was short-lived.  Some JPGs drag and drop.  Other do not.   This one does not.

 Nor this one.
