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.

Your bug however is with the virt-manager flatpak from flathub and needs reporting there.

I installed the Virtual Machine Manager directly from Discover. That's why I assumed that the message about “bugs” must be running.
