If someone might also confirm of this little bug I mentioned here and knows better than me, he may just file a little bugreport to the developers of KDE. Maybe he also nows a little workaround???
[Ctrl+Alt+F8], [Ctrl+Alt+F7] work fine for me to switch between user sessions (minimal KDE, LightDM, amdgpu). I usually start new sessions using "dm-tool switch-to-user USER", sometimes I do it from KDE screen locker. I have not noticed any issue with unlocking user session from kscreenlocker password prompt or from lightlocker for fluxbox.
However what is broken in bookworm is unlocking user session from DM login prompt. Sometimes existing session is terminated and I have to login again. I have seen it with LightDM and SDDM, in qemu and without virtualization. A workaround is to leave DM greeter running after logout and to switch to another session using [Ctrl+Alt+F<n>].
On my old laptop LightDM greeter reliably switches to the plasma session started for the selected user and unlocks that session. Currently Kubuntu-20.04 is installed and I do not remember any problem with 18.04 or 16.04.
