Why did you have to upgrade?
Some apps that I need to run has min req of 10.14.
Anyways I tried to update my Multibeast and after restart now I'm blind. Well the display does not seem to work, audio seems like working so pretty sure its loaded.
I have not even tried to upgrade just wanted to update Clover lolThen I would suggest you upgrade to Mojave and stay there for the moment.
The latest version of Catalina seems to have quite a bit of problems even for real Mac users :
