Theme breeze-openSUSE cannot be loaded.
file /usr/share/sddm/themes/breeze-openSUSE/Main.qml.12.1
plugin cannot be loaded for module ‘org.kde.plasma.core’
cannot load library /usr/lib64/qt5/qml/org/kde/plasma/core/libcorebindingsplugin.so
(lib64/libQt5Gui.so.5 version ‘Qt_5.15.8_PRIVATE_API’ not found (required by /lib64/libKF5IconThemes.so.5))
That reads like an incomplete upgrade. Leap 16 is largely Qt 6–based for Plasma, while Leap 15.6 is Qt 5. Seeing Qt 5 libraries trying (and failing) to satisfy newer KF5 components means the upgrade didn’t finish cleanly and the system is now in an inconsistent state.
Switch to a text console (eg Ctrl+Alt+F3), and check that the repos are now all Leap 16… zypper lr -u
If you are in doubt or need help making sure that the repos are correct, post here with the details as best you can.
If the repos are ok, and assuming that you have internet connectivity, run
Here the output of sudo zypper lr -u
I guess that some repos are missing.
Repository priorities are without effect. All enabled repositories share the same priority.

The repos #1 should be openSUSE-Leap-16.0 and not openSUSE-Leap-15.5 because I tried to install 16.0 from usb disk before I switch to opensuse-migration-tools.
I switch to the opensuse-migration-tools because the installer don’t let me import the existing mount points.
