Public bug reported: Flatpak seems to have serious issues on kubuntu 20.04, at least with some applications that immediately hang when a file dialog is shown.
One of them that makes the issue well reproducible for me on kubuntu 20.04 is shotcut (https://www.flathub.org/apps/details/org.shotcut.Shotcut). Just install it and then press the "Projects Folder" button in the "New Project" to make the app hang. Trying the more recent flatpak on the ppa:alexlarsson/flatpak ppa, which is at 1.10.2 provides a slightly less catastrophic outcome, since the app doesn't hang. However the "open" button of the file dialog does not work and the dialog cannot be closed. The issue may have to do with the xdg-desktop-portal-kde rather than flatpak itself.
