Looking at the error messages you are either targeting a very old iOS version, or setting the minimum iOS version to something low, or there are some references to asset files somewhere or missing. Without more details its impossible for us to track down where it might be going wrong.

I'm pretty confident that this is not a potential issue in the .NET MAUI SDK but with your project setup. Especially since you are setting these:

		<EnableDefaultResizetizerTargets>false</EnableDefaultResizetizerTargets>
		<MauiEnableStoryboard>false</MauiEnableStoryboard>
		<MauiSplitMauiResizetizer>false</MauiSplitMauiResizetizer>
		<MauiUseLegacySplashScreens>true</MauiUseLegacySplashScreens>
		<MauiExplicitPlatformSplashImage>false</MauiExplicitPlatformSplashImage>

Then you will have to make sure all the assets are correct. Double-check your info.plist and the info.plist that actually ends up in your app bundle, along with the assets etc.

Unfortunately, I don't think there is much we can do on our end.

If you do think this is a bug in the .NET MAUI SDK, please let us know why you think that. Thank you and good luck!
