KDE issues with fresh install


I’ve installed the latest stable version of Qubes and switched to Plasma.
When I restart in XFCE the restart works fine, in KDE it hang with a black screen.
In XFCE(I’ve edited keyboard.sh, qubes-keymap.sh inside the template and added languages in the settings of XFCE) my keyboard layout is working with 3 languages, but in KDE it does not.

Anyone can relate?
