Looks good.
Have you looked? 😁
Is there any hope?
So that rules out blindly renaming it for the purpose of KDE reset.
How can you do that?
Is ~/config only for KDE or does any other application use it to save configuration files?
I am still on KDE 5 with PCLinuxOS.
Then what does it actually use? Is there a way to help the person asking the question?
In the /home directory, there should be a hidden directory called .kde which mostly contains KDE settings for your user. Rename it and check. A new one might get created with default settings during next login.
Caution: I am no expert and consider all backup options before doing this because it may force you to re-install.
Edit 1: based on additional searching due to comment below, it was ~/.config for KDE 5. I have no idea of what it is for KDE 6. May be you will have to go through source code to find.
Thanks, I may try it sometime. I have a Neon installation in one of my partitions already.
