macOS 11.01 not updating to 11.2

Hi,
the macOS installer will reboot the target (guest) and then sequence through a start-up with a progress bar. What caused me to learn the "Stop" scenario was two fold, but I waited patiently for the bar to have no progress for about an fifteen minutes to a half hour. At that point I would stop the guest, and restart. The restart would then work. (super caveat - I never tried on any 12.x version)

I recall doing that as well on 11.x, but now on 12.x, it just reboots quickly without hanging as you described.
