AppStore icon becomes Full black

App binary rejected and message is as following

Guideline 2.3.8 - Performance - Accurate Metadata

We noticed the app icon displayed on the device and the large icon displayed on the App Store do not sufficiently match, which makes it difficult for users to find the app they just downloaded.

Next Steps

To resolve this issue, please ensure all your app icons are finalized and similar enough to each other to avoid creating confusion. When users search for your app on their devices, they should be able to recognize it from the icon on the App Store.

1.When I click Choose File the app-icon shows perfectly

thereafter selecting a build, it again changed to fully black coloured icon

EDIT Note: I tried without choosing icon manually in iTunes connect, added 1024 image in assets is Automatically selected and shown as App Store large icon, again icon becomes full black.

I found a solution, Just delete AppIcon from Appstoreconnect webpage, It will automatically accepts 1024 image added in Appicon file in the bundle.
