Plasma 5.25.5 theme issue

Had the same thing this morning, xdg-desktop-portal-kde dumped core. Restarting the service (and possibly browser, don’t remember exactly) fixed it for me: $ systemctl --user restart plasma-xdg-desktop-portal-kde.service

If the service is not enabled by default, then enable it with

systemctl --user enable --now plasma-xdg-desktop-portal-kde.service
