Greetings! It appears that you are setting selective optimization on a Display campaign. This was never documented as being supported. Setting selective optimization was meant for app-based campaigns. There was a recent upgrade in your Google Ads account that caused the API to recognize this unexpected request and reject the request since it was not formally supported in the first place.
I'm currently chatting with my fellow engineers to see what the next steps are for possibly turning selective optimization on for Search and Display campaigns even if it was not formally supported before. I'll keep you posted.
