How I can I reinstall the default KDE desktop?

I have a laptop, and last night I found that I placed the battery monitor twice in the bottom panel. I tried to delete it but that didn’t work.

Now all the widgets are hidden and there’s a big almost white square (60%-70% opacity ) over the “home” desktop shortcut.

How klutzy? My excuse is that I was using the laptop on a stool with the mouse on a non straight surface. I should have moved the laptop to a table before trying to do these things.

Is there a way or restoring the desktop to the default, no extra shortcuts and the default bottom panel?

Thanks

1: logout from your desktop.
2: Get to a command line while not logged into your desktop:
2(a): You can use CTRL-ALT-F1 to get a terminal session and login there; or
2(b): You can login to Icewm at the SDDM login screen. That’s still a desktop, but a minimalistic one that doesn’t depend on what you will be fixing. There’s an icon to open an “xterm” window.
3: At the command line, from your home directory

 rm -rf .config .local

If you prefer, you can instead use

 /usr/bin/rm .config .local

The second version avoids shell aliases, and won’t prompt for confirmation.

4: logout from your Icewm session or your command line session. You can use CTRL-ALT-F7 to get back to a GUI interface if needed.
5: login to KDE/Plasma. That should recreate your desktop from scratch.

If it’s only the panel then it should be sufficient to just remove ~/.config/plasma-org.kde.plasma.desktop-appletsrc

Worked, thank you for the help
