Desktop (please complete the following information):

• OS: Ubuntu 24.04.1 LTS
• Desktop Environment, if applicable (on Linux): Gnome
• Version 46.0.1

Additional context AppImage originally not working due to the current issue in AppArmor (Launchpad Bugs #2046844, #2064672 (SRU'd fix for Noble), and #2072811 (the regression bug that reverted it)). Could make AppImage starting with "sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0", but app stalled at the spellcheck download.

Application works when started by doubleclick on the AppImage in the file manager.
