When I connect the camera I get a popup asking if I want to open the 
File Manager. When I click "yes", a generic-looking window with the
title bar showing gphoto2://Canon_Inc_Canon_Ditital_Camera_[long hex number]
This has been happening since I started with Raspberry Pi some years ago.

The "application wants to use the camera..." popup was standalone and
unlike the file manager and gphoto windows. It really looked like a
system dialog box similar to the "system is up to date" box that appears
after an upgrade from the desktop title bar menu. Except that it
appeared some time (hours?) after an upgrade.

If by DE you mean desktop environment, I'm using whatever comes with 
Bookworm, with no concious customizations. There's nothing like Skype
or Zoom in the Raspberry menu. The Chromium browser was running, and
a bunch of LXterminal windows. 

Thanks for writing!
