My current Catalina MBP (and all OS since I bought that machine) apparently cannot handle multi-users well.
Constant strange bugs, flashing login screens and freezing apps (if used by multiple users). Changes to settings cause password/TouchId confirmation popups for the other user that block the system.
If I am logged into two accounts, opening the MBP will show a login screen for user A, then open the desktop for user B (didn't want to see that), then quickly flash to a login screen for user B and upon entering the password/TouchId flashing back to the main login page and voila, you can finally login as expected.

It's so strange.
