Permission Error When Saving Formal Review in RQM 5.0.2

I am getting the same issue seen in this older question
But the answers in that post do not help. Does anyone have any other suggestions? We are not using Teams, and modified the permissions for two of the items, but I'm still seeing an error for Setting Up Work Item Approvals. We cannot find that anywhere, so I'd love some suggestions - thanks!!!
