I have the exact bug that is listed here on my laptop.
https://bugs.kde.org/show_bug.cgi?id=500927#c11
The clipboard (klipper) will let me copy a single thing, and then will ignore all future copy requests until I manually clear it.
If I copy without interacting with plasma in any way, it works, but as soon as I interact with plasma, the paste will revert to whatever the klipper has stored.
I have tried setting the following environmental variable with no change.
QT_QPA_PLATFORM=wayland
I have tried installing wl-clipboard without any success either.
Setting klipper to a single level of memory doesn't even fix this issue.
I'm totally out of ideas, any advice or help would be very appreciated.
linux 6.18.5.arch1-1
plasma-workspace 6.5.5-1
wl-clipboard 1:2.2.1-3

So, I just went through and did a huge clean out of packages installed from the AUR and this has resolved the issue.
I had a bunch of packages in there such as:
kguiaddons-git
kconfig-git
Ki18n-git
and such, I was suspect on anything that was a *-git package and nuked it.
I had to remove most of these with 'pacman -R -dd' as they were triggering dependencies with many KDE apps.
WARNING: be sensible, you can probably break countless things using -R -dd with pacman.
I then reinstalled them from the official repos via 'pacman -S'.
Then I did a full update and reboot and it is now working. I am guessing there was something in here that was significantly out of date and causing these issues.
Why I had these, I honestly can't remember, this is the noob corner after all.
