[SOLVED] update of qt to version 6.10.1 has broken kde plasmashell

Hello, it seems that the update of qt to version 6.10.1 has broken kde plasma.
After updating qt, Plasmashell is cyclically restart several times and give black screen
Kwin and other app still work, but not plasmashell. I have installed all currently available updates.

plasmashell --replace output the following message:

kf.plasma.quick: Applet preload policy set to 1

It appears that some of the packages have not yet been updated or need fix.

qt 6.10.1
plasma 6.5.3.2
wayland
proprietary nvidia driver  580.105.08
thank you for your attention

/home/username/.local/share/plasma/plasmoids/org.kde.weatherWidget-3/contents/ui/main.qml:67 looks like it's some 3rd party widget - what if you remove that?

thank you for your reply, it seems that the plasma-workspace package has not been compiled with the new qt version and this causes the problem
