Check this message by @kwalter, from a few pages back: he had a similar experience when upgrading to Catalina:Hi All--
I followed the instructions before attempting to update to 10.15.1 (as well as copying over the latest versions of VirtualSMC, AppleALC, and Lilu). After which, I have attempted running the the upgrade multiple times. Each time, the system does a reboot, and after I log back in, the 10.15.1 upgrade notification reappears and prompts me to update.
"Phew!! I got there in the end - I was booting from the wrong volumes each time.
I was starting off with 'Install from Mojave' and it should have been 'Preebooter from Preeboot', then 'Filevault Preeboot' then final install. Do it right and it goes extremely smoothly "
IF you haven't already, try using the steps suggest abote, this may help.
