I am on maui 9.0 SR6, still have the same issue. But the issue filed on the maui reposotory is closed and locked. After some investigating, I found I have to remove the "CFBundleShortVersionString" from "Platforms/iOS/Info.plist", then everything works as expected. This behaviour is not documentd here: https://learn.microsoft.com/en-us/dotnet/maui/ios/deployment/publish-cli?view=net-maui-9.0

    <key>CFBundleShortVersionString</key>
    <string>x.x.x</string>
