IOS will NOT build with Unity Monetization installed

I have had two projects with this issue since upgrading to Unity 2019. Everything builds fine on Cloud Build for both Android and iOS until I add the Unity Monetization 3.0 from the asset store. After that, Android builds fine, but iOS fails every time.

I've removed the "Ads" package from the package manager, removed multiplayer from the package manager, and made sure everything is set up in Unity properly.
I use Cloud Build for the iOS builds so I can do them on my PC, but now iOS fails every time. And after uninstalling the "Ads" and "Muliplayer" packages from the package manager, it fails with no error codes.
If anyone can help me to fix this, I would much appreciate it.
