Errors Troubleshooting, launchging kdevelop

I have a serious problem, I have installed KDevelop

and error, one icon is “stuck” in my task bar

How can I fix this error

You’re missing the correct version of the libksysguard package.
I don’t see how this is related to kdevelop.

I found the solution,

First Step, right click of mouse in

taskbar, then click on widgets

Choose Widgets, use of notification

click on erase broom, then click again on

Widget Notifications, success the taskbar is case closed
