Just updated and now all of a sudden xdg-desktop-portal-kde cannot start.
Running KDE on x11.
This also causes dark themes to not work anymore and theme is white in some apps like firefox that use xdg-desktop-portal to get system theme information.
Issue is temporarily solved by running:
systemctl --user restart plasma-xdg-desktop-portal-kde
It will need to be done each login until the bug gets corrected.
