I'm experiencing an InvalidCastException in .NET MAUI 9 that occurs only in Release builds when navigating to a Shell page after adding Android Auto support. The error doesn't occur in Debug builds. The app was working fine before adding Android Auto support, but now crashes when attempting to navigate to a shell page.

What I've Already Tried
Changed AndroidLinkMode to SdkOnly and to None (app stopped working)
Tested Debug Mode (works perfectly)
