MvvmCross 9.0.1 iOS release build crashes on device

🔙 Regression

A release build (IPA file) of an an app crashes as soon as a MvvmCross package reference is added.

Reproduction steps

1. Create a new app with dotnet new ios

2. Set a valid bundle identifier in Info.plist

3. Add a reference to MvvmCross, version 9.0.1 or 9.0.0

4. Build an IPA file: dotnet publish testapp.csproj -f:net6.0-ios -c:Release /p:CodesignKey="Apple Development: Markus Palme (XXXXXX)" /p:CodesignProvision="Test app" /p:ArchiveOnBuild=true -r ios-arm64

5. Install the IPA file on an iPhone, start the app

6. The launch screen shows quicky, then the app crashes with this message being visible in the console:

   

   error: Failed to load AOT module ‘System.Private.CoreLib’ while running in aot-only mode: doesn’t match assembly.

@markuspalme not a lot of experience with net6-ios. Have done a bunch with net6.0-android, which works well.
