Contacts quitting unexpectedly. Recently updated to 10.15.2

Hello.

I went through all the suggestions in the previous string; start in safe mode, open Contacts in safe mode, removed com.apple.AddressBook.plist and restarted. Still having the same issue. I'm able to start Contacts, but the moment I try to type a name in the search blank, it quits. At first, it would barely stay open a minute before quitting.

Safari also is acting "squirrelly".

Help!
