launch program

Additional info:

tried removing all plugins and contents of
~/.config/calibre
~/.local/.../calibre
and 
# dnf remove calibre
followed by
# dnf install calibre

so fresh install does not help.

I experience the same error. A re-install didn't help either.

Update

Trying to install older fc32 builds from https://kojipkgs.fedoraproject.org/packages/calibre/ didn't work. They either installed and failed to start with the same error or had dependency problems.

I was able to install calibre-4.16.0-2.fc33.x86_64 by:
$ sudo dnf remove calibre
$ sudo dnf install calibre --releasever=33

After that calibre works (but I hope I didn't make my Fedora installation too Frankenstein).

P.S. Dependencies such as python3-qt5-webengine moved from 5.13.x to 5.14.x, maybe it's the latest 5.13.x. Don't know how relevant that is.
