Created attachment 145101 [details] Removing second Kickoff launcher renders first one empty If you add a second kickoff widget on panel or desktop then remove it, the first kickoff becomes empty, and the user should select another alternative then revert back to kickoff to make working again.
Cannot reproduce on 5.24 (git version). There are many fixes on the application launcher that are not backported to 5.23. Please test again on 5.24 after it's released and feel free to reopen the bug if the issue persists.
