Bug in Apple Contacts data entry in Big Sur OS
I downloaded and installed Big Sur 11.5.2 last night, and the Contacts bug identified many months ago is still there, still preventing users from adding new contacts. It's past time for Apple engineers to prioritize this issue and fix it. The Contacts app is a vital component for millions of Mac users, and the inability to keep it current devalues it considerably. The problem is well documented: Begin a new entry, type the first name into the top field, and while adding the last name or, sometimes, starting the Title, the whole form disappears, and some unexpected contact from the existing database pops up on the screen. I've tried several of the suggested steps from earlier posts, such as restarting, removing questionable apps from User & Groups in System Preferences, etc., but nothing seems to work. One workaround is to add new contacts from an iPhone or iPad that syncs with your Mac, but that's annoying and not always available.
