Create two CPTs and give each an ACF relationship field with the same name.

Create a Themer Layout Singular for one of the CPTs and include a UABB Advanced Posts / Set the Query to ACF Relationship / Set Pagination to Yes, Numbers /

If there is a related post in the other CPT, it will show. If there is no related post, it will give an error.

If you set the Pagination to Yes, Scroll, the error goes away
