Thanks for the bug report, and I'm sorry we weren't able to get to it yet. Can I ask you to see if the issue is still happening in Plasma 6.4 or later, or I guess with more up-to-date AMD microcode?

I tried the latest KDE neon version  and the problem still occurs (KDE Plasma version 6.4.2, Frameworks version 6.15.0, QT version 6.11.0-29)

The error is coming from Network Manager, which assigns a UUID to each connection.
Can you please run the following and paste the output in a reply? Let us know which entry you're trying to connect to.
