The crash is caused by the GOA panel being disposed prematurely, in get_all_providers_cb: user_data (the panel) is being g_autoptr'd, and as a consequence it is destroyed when exiting the scope of the callback. This appears to be an unwanted regression/side effect of https://gitlab.gnome.org/GNOME/gnome-control- center/-/commit/5579314a38aa3aa26e8f833661fe898d31f327f7.
