Active Directory - Joining With Preexisting Computer Object (Post KB5020276)

With KB5020276, our team members are no longer able to join objects to the domain that were created by privileged team members.

We have two groups: 'Admins' and 'Technicians', our Admins have permission to create Computer objects, and will create preexisting computer objects in the proper OU's, adding the Technicians group to the 'User or Group' that 'can join this computer to a domain'. When imaging, our Technicians will join the computer to the domain. However, with the KB5020276 update, now only the creator of the OU is currently able to join the computer.

Is there an additional setting necessary so our techs can join computers to the domain?

    The user attempting the operation is the creator of the existing account.

    OR

    The computer was created by a member of domain administrators.
