由于某种原因，当我登录到我的盒子并想要启动等离子时，我启动了应用程序，但没有可见的壁纸或面板，并且右键单击时也没有看到上下文菜单。尝试手动启动 Plasshell 给我：
$ plasmashell

这看起来肯定很糟糕：
terminate called after throwing an instance of 'CppUtilities::ConversionException'
what(): unexpected "-" after day
但我还没能解决这个问题，有人可以帮忙吗？

我发布这个答案，而不是删除这个问题，作为可能遇到同样问题的其他人的参考：
我发现问题是由syncthingtray-git我从AUR（https://aur.archlinux.org/packages/syncthingtray-git) 删除 ( yay -R syncthingtray-git) 后，plasmashell开始完全正常，正如预期的那样！
