I am confirming the devogon's problem.
I have just upgraded calibre to 7.1.
Since the upgrade when clicking on the "PDF" next to "Formats" nothing happens (rotating cursor shows briefly).
If I want to open a PDF book I have to right click the "PDF" and choose "OpenPDF with..." then select my (any) dedicated PDF viewer.
"Use internal viewer for PDF" is unchecked.
System opens every PDF file with my designated PDF viewer without problems.
The problem arose only in calibre and right after upgrading to v7.
OS: Ubuntu 22.04.3
