I encountered this error again, and, after some research, I found that "As of iOS 13, UIApplication.shared.delegate?.window has been deprecated. Instead, you should use the SceneDelegate to get the root view controller. If you're targeting iOS 13 and later, you should update your code to handle this.". This attempts to address that (still testing)
