My guess from the MESA-INTEL lines is that there might be a bug in GTK that's causing this. Usually if Recorbox crashes due to an issue in Recordbox code it prints Rust stack trace/error messages. If that's not printing those then often it's something to do with GTK. If that is the case then it's a matter of waiting for a GTK update to fix it, which hopefully would be when I update the runtime to gnome-49. If not there's a few other things it could be so I'll see if I can find anything.
