Lately I am finding that the Kubuntu panel on my Plasma 6.4.2 from beta PPA, but happened on Kubuntu 25.04 supplied Plasma 6.3, hangs about 30 seconds after logon after the desktop has finished loading. It’s possible to interact with restored and loaded windows on the desktop (Firefox, Konsole etc.) but trying to access anything on the panel doesn’t do anything by clicking on apps, accessing clipboard etc. until after about 30 seconds when it all springs back to life with the backlogged clicks activating.
Running journalctl --user -u plasma-plasmashell.service -S ‘2025-07-03 16:34’ or whatever login time is, gives a few errors, but just after the panel springs back to life the journal shows these entries from kdeconnect amongst others:

There always seems to be 7 kdeconnect.interfaces entries in the journal. I have saved the parts of the syslog with the kdeconnect generated from using the extra logging set in the QT_LOGGING_RULES environment from KDEConnect - KDE UserBase Wiki. I have attached.
These log entries were generated whilst my iPhone is locked.
My iPhone running IOS 18.5 and KDE Connect version 0.5.1 (1) has paired successfully and can communicate with the PC.
Operating System: Kubuntu 25.04
KDE Plasma Version: 6.4.2
KDE Frameworks Version: 6.14.0
Qt Version: 6.8.3
Kernel Version: 6.14.0-23-generic (64-bit)
Graphics Platform: Wayland
Any ideas on how to debug this further gratefully received, but please remember that I am just an novice at this.
I have apt purged and removed the .config entry for kdeconnect to start with a new configuration after reinstall.
The ufw firewall has the suggested entries in it from the wiki.
