Aha! This *is* an artefact of something strange on my system; namely, I
was starting gnome-control-center from a terminal emulator packaged as a
snap; as such, it has a LD_LIBRARY_PATH specified, which was partially
overriding library resolution.
Weird that this manifests as the application
gnome-control-center doesn't crash for me when I tried your test case.
Can you reproduce this from the live ISO or from a clean install?
Is there a crash report for this issue in /var/crash/ ?
