Missing prvReadCustomControlDefaultConfig privelege

Hello everyone,
We recently refreshed our DB and updated our On-Prem CRM from 8.1 to 8.2. After doing that , we are umable to remove System Admin security role for users.
User 1 is a system admin and is trying to remove System admin from User 2.(User 2 has other security roles as well. Just system admin is being attempted to be removed).
An error is thrown.
