iMac Pro won’t start after update.

My iMac Pro will not fire up. The last time I had it on, there was a notice that a new upgrade will be installed over night. It all happened so fast as I was closing down and I wasn’t able to catch the full notice but I think it included iMac os something? Help!

MacBook Pro 13″, macOS 11.2

Shutdown via Power Button and disconnect all external drives. Restart and Immediately hold - Shift - Key. It will do a repair Disk, clear cache files and only load Apple Software and Fonts. It is going to load slowly - Normal. If all goes to plan - this may allow the update to finish installing and finally reboot normal.
