I'm trying to update my current MS Store App by submitting and updated version of the program that has been built using .NET Maui , however I am getting an error message that I cannot resolve when the new version is being uploaded to the store and validated. It doesn't pass validation for the store with the following errors.

A previous submission for this app was released with a Windows Phone 8.1 or Windows 8.1 .appxbundle, so your Windows 10/11 submission must use an .msixbundle or .appxbundle.

A previous submission for this app was released with a Windows 10/11 .msixbundle or .appxbundle. Subsequent submissions must continue to contain a Windows 10/11 .msixbundle or .appxbundle.

I have tried multiple configurations when I create the package, here are the steps.

Project->Publish->Create App Package->MS Store->Select and Configure..Publish Profile->MSIX-win10-x64.pubxml.

How do I get the correct package to be a "msixbundle " ?
