I still get the same problem when running qtractor on this machine as I reported for the other one, which is running an older version of qtractor and Ubuntu Unity 20.04.
Under Ubuntu Studio 23.10 I am running the latest development version of qtractor, but I haven't yet managed to get this to compile in the Unity versions.
I don't know whether the canberra reference is crucial. When I do 'aptitude search canberra' there is no mention of a possible canberra-gtk-module, but I tried installing libcanberra-gtk-module to see if it helps. It got rid of the Gtk-Message, but qtractor still crashes as previously reported.
On a Ubuntu Unity 22.04 machine (not the one I normally use for qtractor) the output I get from 'qtractor --version' is:
Gtk-Message: 12:14:16.086: Failed to load module "canberra-gtk-module"
Qt: 5.15.3
Qtractor: 0.9.25
