App Store Submission Issue: Missing App Icon (1024x1024) Despite Being Included in Asset Catalog

Missing App Icon (1024x1024) Error During App Store Submission

Hello everyone,

I'm encountering an issue when trying to distribute my iOS app using the Transporter tool. The submission process is blocked by an asset validation error stating:

Asset validation failed (90704): Missing app icon. Include a large app icon as a 1024 by 1024 pixel PNG in the asset catalog of apps built for iOS, iPadOS, or watchOS. Without this icon, apps can't be submitted for review.

I’ve tried several workarounds:

• Added the ForegroundFile and Color properties to the MauiIcon.
• Resized the image to 1024x1024 and included it in the bundle.
• Verified the settings in my .csproj file and Info.plist.

Despite these efforts, the issue persists. Could anyone provide guidance on what to inspect within the contents of the generated IPA file or suggest any other solutions?

I've added the relevant project files and info.plist for reference.

Below is the .csproj file:
