I have a 2019 27" iMac, and my contacts database is at least ten years old. I can't add a new contact using Apple macOS Ventura built-in Contacts app. This was a problem in Big Spur, but I never fixed it. I only used a workaround of entering new contacts via my iPad or iPhone.

Greetings Gary Denning,
Welcome to Apple Support Communities. Let's make sure that you have the proper steps to add a contact using the Contacts app on your Mac. Follow the guidance per the Apple Support app:
Add people and companies to Contacts on Mac
Let us know the outcome, and we can go from there if needed.
We hope this helps you.
Take care.
This sounds very much like the Contacts application is using a Third Party Service as its' source.
If so, disable the Sync process for Contacts application.
Add the information into Contacts application.
Will it go in without any issues ?
If so, presto.
This may answer the users' issue >> Third Party Source for Syncing Contacts
I am having the same issue. I have tried 4 or 5 times to enter a new contact, and after I enter the company name and phone number, it immediately takes me back to a saved contact.
I do not believe I am syncing with any third-party services, at least iCloud is the only thing listed Settings> Accounts
Uncheck Contacts from Syncing with iCloud.
Restart the computer and pause 10 - 15 seconds.
Readable Contacts to iCloud.
We are trying to Force a re-sync.
Still having issues, Sign Out Of iCloud completely.
Restart the computer
Re Sign into iCloud and allow all applications to sync again.
Additionally (since I couldn't update the previous reply):
This gets more confusing. Looking at the Contacts app on my Mac, when I went to All Contacts it showed the 5 attempts with the various bits of data, and that was synched to my phone and watch, though all were incomplete. I then signed into iCloud.com and entered the full record into my Contacts there, but that has not yet synched down to any of my devices.
On my Mac, I disabled the only Account (iCloud CardDav) and then I was able to fully enter the contact company and all of its details. But that one will not sync anywhere. So somehow I seem to have two different iCloud versions of things although they are all signed in with the same account (email/password).
Never experienced this until I added a new M1 MacBook to the stable (the old one on BigSur still plays fine, as does my work MacBook on Ventura).
That seems to have done it, thank you!
Everything seems like it is synching to the new Mac again.
welcome
