Sorry, it's on Russian: "Буфер обмена" = Clipboard "Громкость" = Sound volume "Обновления программ" = Programs updates "Подключаемые устройства" = Plugged-in devices "Принтеры" = Printers "Системные уведомления" = System notifications "Батарея и яркость" = Battery and brightness "Сети" = Networks
I've worked it around by deleting Klipper's log: 1) reboot up to Login Screen (SDDM) 2) switch to text console and log in as root 3) cd /home/user/.local/share/klipper && mv history2.lst history2.lst.bak One of previous steps was to delete /home/user/.cache , but it didn't help.
