sudo pacman -R kholidays5 kxmlgui5 kcompletion5
KDE packages have been renamed recently, in readiness for Plasma6 in January. I can see this is particularly troublesome here.

would it be easier to reinstall KDE?
OK. Is a complete reinstall an option for you?
may be the easiest way out. What command?
It’s not that easy. You’ll need to download the latest ISO and install from scratch. Which do you want, XFCE or KDE?
quite happy with XFCE. But please tell me all I have to do, don;t want to get into a bigger mess 
Well, to start with, you’ll probably want to save your personal files to a USB drive, as reinstalling will destroy everything. You can download the ISO here. Boot with it, and follow the installation instructions of the installer. That’s really all I can offer from this point forward.
Except, download the full ISO, not the Live one.
OK thanks. I’ll try to do this when I have time. Is it not possible to keep my ‘home’?
Is it on a separate partition?
yes, it is
In fact I think it is…with all other distros I had a special partition but I didn’t install this one
