NSCocoaErrorDomain Error Code 4

I am on MacOS 15.3.2, XCode 16.2 I have a MacOS app with app group and Widget that was working on Sonoma. I am aware of the App Group changes with Sequoia, and I think I have that right. The app runs fine. The widget refuses to load in the simulator and in the system. The simulator error I get is Failed to load widget. The operation couldn't be completed. (WidgetKit_Simulator.WidgetDocument.Error error 4). I am having trouble finding out what exactly error 4 means. Can anyone help?
