'Start' menu error after updating to Fedora 43

,

I’m getting an error every time I click the start menu after updating to fedora 43 (running kde plasma)

The error:

file:///usr/share/plasma/plasmoids/org.kde.plasma.kickoff/contents/ui/main.qml:21:1: Cannot load library /usr/lib64/qt6/qml/org/kde/plasma/private/kicker/libkickerplugin.so: /lib64/libKF6Runner.so.6: undefined symbol: _ZN14KWaylandExtras18xdgActivationTokenEP7QWindowRK7QString

Tried this:

sudo dnf --refresh update

Nothing to do.

Not sure what to do next.

Please, if you can, when making suggestions speak as if you’re talking to a young child, or a golden retriever. I’m no linux guru.

Thank you!

There is another tread that helped me with what seems to be the same issue.

TLDR: Downgrading the Kf6Runner with
sudo dnf downgrade kf6-krunner
fixed it for me
