Hi,
I installed the KDE plasma upon my GNOME 40 since I really fed up with Gnome. I know this is a bad way of installing KDE but I had no other options, I could not create a new user for KDE, since I need to preserve some user access permission for my work user account.

then I removed gnome from the machine and removed my .config, hoping the KDE would start as factory settings.
But when I try to use KDE settings manager, my UI is garbled, text is not readable, I chose Breeze as global theme, however the font color is not readable and not exactly what it should be from the latest KDE Plasma UI.
I need a bit help on how to launch the KDE default setup, I tried to remove the /home/user/.config file but still not effect.

thank you for your help - screenshots below
