I have the same issue here, I have just upgraded it today. I also noticed that krunner (alt+F2, alt+space) also fails to load, which may be related, but not want to overload this issue.
I’ve executed the following commands:
dnf provides /usr/share/plasma/plasmoids/org.kde.plasma.kickoff/contents/ui/main.qml
dnf provides /usr/lib64/qt6/qml/org/kde/plasma/private/kicker/libkickerplugin.so
This revealed that these are from the packages:
plasma-desktop-6.4.5-1.fc43.x86_64 : Plasma Desktop shell
Repo : @System
Matched From :
Filename : /usr/share/plasma/plasmoids/org.kde.plasma.kickoff/contents/ui/main.qml

I’m going to execute sudo dnf reinstall plasma-workspace plasma-desktop command, to reinstall these packages, but this topic is very hot right now, so I try not to overload by further comments, unless addressed. I’ll try downgrading after this, but I believe I’ll need to restart after this.
I also need to accept a new PGP-key, it seems:
0x31645531 OpenPGP-kulcs importálása:
Felhasználó: „Fedora (43) <fedora-43-primary@fedoraproject.org>”
Ujjlenyomat: C6E7F081CF80E13146676E88829B606631645531
Tulajdonos : file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-43-x86_64
Is this ok [y/N]:
Update: Just reinstalling the packages didn’t work.
