I have a similar stack trace ending with 'cc_display_config_dbus_generate_cloning_modes' and gnome-control-center-44.3-1.fc38.x86_64, while trying to configure mirror mode with a newly plugged-in HDMI overhead system. The default is split (side-by-side),and I'd like the external HDMI system to mirror my LCD display instead.
