I just updated in a KVM virtual machine. And it never completed startup.
It looks as if GDM is failing to start.
I rebooted (with CTRL-ALT-DEL), used ‘e’ in the grub screen to boot to level 3. That got me in at a command line. I then switch the displaymanager to SDDM. And it seems to start up normally with SDDM. And, yes, I can login to Gnome using SDDM.
