Status changed to 'Confirmed' because the bug affects multiple users.

I get this error message when clicking in the panel menu on Open webmail startpage. Ubuntu 22.04, latest ayatana-webmail version from the repositories (22.2.26+dfsg1-1).

Update: For me the error disappeared after a simple reboot.
After installation I could the tool get running only after installing the package gir1.2-ayatanaappindicator3-0.1 (see my report https://bugs.launchpad.net/ubuntu/+source/ayatana-webmail/+bug/1972089). Maybe after doing that a reboot would have been necessary in order to get it run smoothly.
