Comment 38 for bug 1949340

Hello,
also impacted here :)
Ubuntu 22.04 + a few different Window Manager (my main is i3wm, and here is the initial investigation: https://github.com/i3/i3/issues/5059)
Programs affected by the issue are Firefox and Chromium.

On this thread a temporary workaround has been found for Firefox while waiting for the fix
https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1968887
set the `widget.use-xdg-desktop-portal.file-picker` to `0` in the `about:config` in Firefox.

Thanks in advance for the work :)
Cheers
