I would suggest the following solution but you need to take care of it from Macbook which is using same Apple ID.
It is best to always have a backup before attempting something like this
Open the AddressBook folder located on:
~/Library/Application Support/AddressBook
In that folder, you will find three files:
a. addressbook-v22.abcddb
b. addressbook-v22.abcddb-wal
c. addressbook-v22.abcddb-shm
Delete them.
- Open Contacts and your list of contacts should quickly populate as the index is rebuilt.
