From Unstable… There was a point some weeks or so past that there seemed to be some instances of xdg-desktop-portal either failing or failing to start … restarting the service would fix it, and it hasnt been continued to be noticed recently (after some updates). systemctl --user status xdg-desktop-portal systemctl --user status plasma-xdg-desktop-portal-kde systemctl --user restart xdg-desktop-portal systemctl --user restart plasma-xdg-desktop-portal-kde
