Рабочий стол Kubuntu зависает после установки виджета календаря событий

Я установил виджет календаря событий вручную через git clone и добавил его на верхнюю панель, и мой рабочий стол начал зависать и все виджеты на панели и файлы на рабочем столе не активны.

• ОС: Kubuntu 20.10 x86_64
• DE: Plasma 5.19.5

После перезапуска док-станция Latte не отображает значки, но всплывающие подсказки отображаются при наведении курсора.

Я выполнил команду killall Plasmashell && Plasmashell , и это показывает:
