Cannot start Control Center
If I open the URL „settings:/" in Konqueror it remains empty. So I have no access to the settings.
What might be wrong?
Regards and thanks in advance,
Michael

Re: Cannot start Control Center
That looks like a sort of configuration mess at user level. You could try to reset the user profile configuration https://www.q4os.org/dqa011.html#desktop.7

Re: Cannot start Control Center
Run this in Konsole - it'll get you to Control Panel
konqueror --profile "ctrl_panel" --icon "kcontrol" --caption "%c" settings:/

Re: Cannot start Control Center
Yes, thanks, it opens konqueror with „settings/" but it remains empty.
The output is:
michael@koekalt:~/Schreibtisch$ konqueror --profile "ctrl_panel" --icon "kcontrol" --caption "%c" settings:/
tdeio (TDEIOConnection): ERROR: Header read failed, errno=104 (pid 8276 process "nit]")
tdeio (TDEIOConnection): ERROR: Header has invalid size (-1) (pid 8276 process "nit]")

Re: Cannot start Control Center
If the reason is incorrect user configuration TDE, you can create a new user, this will create his folder and set the default settings.
In the console command useradd
( man useradd will display detailed instructions for the command).
Then you can delete it.

Thanks to @all!
I solved it with this useradd command.

Re: Cannot start Control Center
I will write in a separate post.
You can simply return the TDE settings of the first user to those set during the OS installation.
Enable viewing of hidden files in konqueror, rename the .trinity settings folder (add 1, for example 1.trinity) and restart your computer.
On boot, a new .trinity folder will be created with default settings.
If you want to return to the original, rename the folders.

Thanks @aluma, that's correct.

OK. 
Seriously, any application program, not finding its folder at the user, creates it with the default settings.
At a time when the passwords of the root and the first user were different, it was possible to simply delete the entire folder of the latter.
