That shouldn’t happen of course, but you would need to install a debugger (gdb) and make sure you have debugging symbols for GStreamer and glib and glibc, and then run gst-launch-1.0 in gdb to get a stack trace of the crash with (gdb) thread apply all bt (or attach to it after it crashed when it says ‘spinning’).

You could also try a newer version of GStreamer, since 1.20.3 is quite old (current is 1.24) and not even the latest 1.20.x.
