I just completed my iOS project in VS 2022 v17.9.7 and was finishing up by adding my app icons to the asset catalog. I was able to successfully add the icons and now I get an error when I attempt to deploy the app to my physical iPhone 13 iOS 17.4.1 with the error:

I am able to deploy the app to the iPhone iOS 15.5 and iOS 17.4 simulators and the launch icon does display just fine but I did notice that my LaunchScreen.storyboard does not display when the app launches. I’m not sure if this has anything to do with it, but when I was able to deploy the app the the physical device, the LaunchScreen.storyboard did display. Nowhere in my app do I reference [email protected], it’s not listed in the .csproj file, and a seach of the entire project says that it isn’t in the project. I cleaned the solution, close VS, deleted the bin and obj directories, and reloaded and re-compiled the app. Same error. I have no idea how to fix this.

I reported the issue to the Microsoft Developer Community, but I believe they dropped support of Xamarin as of May 24th, 2024, so I don’t think they’re going to assist me. I’m hoping that someone here knows whats going on and what if any fix or workaround there may be. This will be my last Xamarin developed app as I will be moving to the MAUI platform, I just need to get this app out there.
