They’ve made a lot of under the hood changes to Catalina. Particularly in
the area of system security. Yes, downgrading might be something you should ask
Apple about before deciding to undertake it.

I have been giving things much thought and suspect that
rolling back from catalina to mojave might cause more problems
than it would solve. Catalina does something that all unix-based
operating systems really should do and that is to separate the
user space such as your and my home directories from directories
owned by the system.
Oh, they mostly do it but apparently catalina gets
serious about it and has moved files to different places if you
installed it. Downgrading to catalina might cause some files to
be inaccessible to either us users or the operating system which
could create big problems of stuff suddenly failing to work after
the downgrade.
After all the fun and games of rebuilding my system, the
new installation mostly works like it is supposed to. I got
admin access back and created a second account just to be safe so
maybe I should go ahead and recover my files from the backup and
be thankful it works.
I'll need to be careful about that because the last thing
I want is to restore the loss of admin capabilities.
This isn't just something that is geeky and abstract.
Every time you read that message in system preferences that goes,
"Click the lock to make changes." and have to enter your login
password, you are exercising administrative privilege and
temporarily becoming the root user.
Last night, while doing some stuff in the terminal, I ran
the date command and it gave a time two hours earlier than it was
in the Central Standard Time zone plus said Pacific Standard
time.
I had to click that lock three times to get it right, once to
temporarily enable location services and once more to check the
box that allows for automatic time-zone setting based on one's
location as there is no manual way that I could determine to tell
the system Chicago. I live in Oklahoma but Chicago is Central
time with the same Summer Time or Daylight Saving time rules as
most of the Central time zone.
In a couple of minutes, I was in Central Standard Time so
I turned Location Services back off to make the ad droids have to
work harder.
