'Transporter error IOS App Icon 1024x1024 missing

I am developing an Xamarin IOS app on a windows box. I have been developing this app for the better part of two years. To get my app to Testflight, I right clicked on the IOS solution and selected "Show IPA on Build Server". I then went to the MAC and added the IPA to Transporter and uploaded the app. However now I am getting an error stating that the App Icon 1024x1024 is missing. Yet I can plainly see the App Store Icon in the AppIcons. Is there something I am missing for the App Icon? Last year there was a place in the App Store to upload your App Icon. I have been struggling with this for over a week and I have yet to find an answer online or anyone that can help.

The process I mentioned above worked perfect for almost two years. The last time I uploaded to Testflight was June 2021.
