as with Ubuntu snaps, first get rid of flatpaks
# dnf remove $( rpm -qa|grep flatpak)

maybe even

# dnf remove --setopt protected_packages= gnome-shell
# dnf remove PackageKit gnome-software
# rm -rf /var/cache/PackageKit/


virt-manager as user, fresh install?

getent group | grep libvirt
e.g.
usermod -a -G libvirt user
vi /etc/libvirt/libvirtd.conf
.
.
unix_sock_group = "libvirt"
.
.
unix_sock_rw_perms = "0770"
