I got a crash report that Camera crashes on start on Fedora 38 (GNOME/Wayland), and I was able to reproduce the same issue on Fedora 39 (both GNOME/Wayland and GNOME/Xorg) - I don't have a fully functional Pantheon session yet where I can test this, but I don't think Pantheon and GNOME/Xorg should be different here.

On Wayland, there are some Gdk-WARNING log messages, and on Xorg, there are GStreamer-CRITICAL log messages, but the crash that immediately follows those looks similar (null pointer dereference?).

I ran valgrind io.elementary.camera on both GNOME/Wayland and GNOME/Xorg on Fedora 39 and these are the logs that also includes the backtraces for the invalid reads / writes (there seem to be both use-after-free issues and null-pointer dereferences).
