New Yast modules (KDE Qt GUI) does not start after upgrade from 13.1 to 13.2

I have done an upgrade from 13.1 to 13.2 using ‘zypper dup’ approach. I am using KDE desktop.

In new graphical (Qt) Yast modules ceased to start. With attempt to get the command line output I receive the following:

andrey@linux-cvzv:/opt> yast --qt
Run command: /sbin/yast2 inst_release_notes &
terminate called after throwing an instance of ‘YUIPluginException’
what(): Couldn’t load plug-in qt
YaST got signal 6 at YCP file /usr/share/YaST2/modules/Wizard.rb:73
Could not open log file.
/sbin/yast2: line 378: 2801 Аварийный останов $ybindir/y2base $module “$@” “$SELECTED_GUI” $Y2_GEOMETRY $Y2UI_ARGS

Please help to resolve.

P.S> In addition to that after the upgrade I found that keyboard layout switching in KDE also did not work, but this easily fixed.

You seem to be missing the qt plugin.
Which libyui* packages do you have installed?

rpm -qa libyui*

For the Qt YaST you need libyui-qt6 and libyui-qt-pkg6, install them if they are missing.

sudo zypper in libyui-qt-pkg6

(libyui-qt-pkg6 requires libyui-qt6, so just installing the former should suffice)
