The Task Manager is choking while trying to read data for the pinned apps. Which apps do you have pinned? Can you find their .desktop files (they might live in /usr/share/applications, /var/lib/flatpak/exports/share/applications/, ~/.local/share/applications/, /var/lib/flatpak/exports/share/applications/, or ~/.local/share/flatpak/exports/share/applications/) and run `desktop-file-validate` on each of those .desktop files? It's possible one of them is corrupt and we're not handling that properly in Task Manager code.

Hey Nate! Here is the output of the validation of the relevant applications:

> /usr/share/applications
> ❯ desktop-file-validate org.kde.kate.desktop
> org.kde.kate.desktop: warning: value "Разширен текстов редактор на KDE" for key "Comment[bg]" in group "Desktop Entry" looks the same as that of key "GenericName[bg]"
> org.kde.kate.desktop: hint: value "Qt;KDE;Utility;TextEditor;Development;" for key "Categories" in group "Desktop Entry" contains more than one main category; application might appear more than once in the application menu

Thanks. Looks like none of them have any errors, so perhaps my theory was wrong.
