Having problems with my KDE after a while. Can't pinpoint what or why, but the user interface doesn't works properly until reboot, sometimes more than once

I’m using a ASUS notebook (MD570D). Only hadrware change is the SDD, which I replaced for a M.2 type. Was working like a charm, but now some configurations of the system don’t load properly at startup. Sometimes I get a desktop with no icons, just some windows opened and no controls over the windows. It usually solves when I reboot, but it doesn’t suck any less because of it. I was kind of trying to figure out a way of repairing it. Any way, here some data that mey help. Any additional info needed, please do not exitate to hesitate to ask!

Warning: No installed USB configs!

Usually dmesg or journalctl has a clue for this, but maybe won’t be that immediate. You need slowly scroll and read.

Sometimes the KDE user profile gets corrupted. Try to create a new user and see if the problem persists.

Now that you mentioned, this makes sense. I’ll try it and report back.
