Are you sure the Mac is shutdown (at least my Mac mini 2018 has a small light to tell whether it is ON, or OFF. The light is also OFF for a few seconds between dual boots).
Or is it just the display that goes black? ...my Mac mini 2018 did that with its initial Mojave version until (I guess) a firmware update fixed that after a few months. So I initially had to disconnect and reconnect Thunderbolt Display cable to get image on the LG display.
Have you tried to boot to Recovery mode and then re-install on top of the old install?
