I've had the opposite problem: started getting awful freezes on a MBP 2018 running Mojave on the day this latest Catalina version was released. No immediate explanation: cpu/ram/disk load perfectly normal, machine just incredibly slow (think 10 minutes to start up). Exact same behaviour in Safe Mode and nothing obvious after some common diagnoses.

Bit the bullet and finally updated to Catalina, all problems gone. Not sure what to make of this but it definitely resonates with stories of Apple practically forcing updates.
