Thanks for the bug report. To report issues with KDE Linux itself (i.e. installation, OS design, integration, system services, etc), use [invent.kde.org](https://invent.kde.org/kde-linux/kde-linux/-/issues/new), and ignore the scary red banner at the top of the page. Please see this for more information. Thanks. https://community.kde.org/KDE_Linux
