Hello, is English your native language, because if it is, then you might want to read your messages again before posting; if it isn't then you can be forgiven.
Can you start the konsole? (your picture implies you can't)
If you can, follow the following steps.
(1) Open the konsole and enter the following two commands;
(2) kquitapp plasma-desktop
(3) plasma desktop
(4) Do not close the konsole,
(5) Do what causes the issue, one or more error messages will occur in the konsole
(6) copy and paste the results of the konsole here so we can see what exactly is going wrong
Unfortunately my actual skill solving skills are still very unperfected so i can tell you this, but it's likely i've nothing else; So hopefully someone else will be able to look at the error message and help you out
