Adressbook mysteriously disapear


Adressbook mysteriously disapear… since friday,
I see a error when dav connect to nextcloud to synchro my addressBook.
When I look on the UI no more addressbook “Contacts”, I only see recently contacts 3, these 3 look good. Like if every contacts are here but under the hood
I connect to DB, I can see my contacts


On the same server for another user, everything is fine

“REPORT /remote.php/dav/addressbooks/users/myname/contacts/ HTTP/1.1” 500 1464 “-” “DAVx5/4.0-ose (2021/10/13; dav4jvm; okhttp/4.9.1) Android/11”

How can I make this addressbook “Contacts” appear on the UI and make them available for sync.
