I continued my search for bugs involving Xwayland and found this one https://gitlab.freedesktop.org/xorg/xserver/-/issues/1052 Under wayland, I launched Yast from krunner; it is in qwerty. – In konsole as root (su + password) I did : export QT_QPA_PLATFORM=wayland ; yast2 --qt – And there, pleasant surprise, it is in azerty. A little extra progress.
