Thanks for reporting this bug with KDE Linux. Since this looks like it's probably due to something not being installed that's present on the Live CD, please report this to the KDE Linux project. Please see this for more information: https://community.kde.org/KDE_Linux > To report issues in the KDE Linux operating system itself (i.e. OS design, integration, system services, etc), use invent.kde.org, and ignore the scary red banner at the top of the page.
Thank you for your comment. I have created new issue on invent.kde.org. https://invent.kde.org/kde-linux/kde-linux/-/issues/428 So, I will close this issue.
Closed.
