我在運行 kontact 時遇到了麻煩：
透過以下方式安裝：
sudo flatpak install flathub org.kde.kontact
輸出：
/usr/bin/flatpak run --branch=stable --arch=x86_64
--command=kontact org.kde.kontact
Trying to create ksycoca...

Kontact 正在啟動，但沒有連接到我的dav calenderst/聯絡人（透過nextcloud 實例），所以看起來好像是第一次運行（有趣的是，在設定中，我的日曆/聯絡人正在顯示，並告訴我一切都準備好了，並且同步中）
有什麼建議我可以解決這個問題嗎？
