TestFlight - app crashes immediately on launch.

I developed an app with the MAUI framework. The app works fine in debugging mode, but when switching to release mode with a distribution certificate and uploading it to TestFlight, it crashes immediately on launch


Specifically, this issue happens after updating the MAUI .NET framework from .NET 8.0 to .NET 9.0 and Xcode version to 16.4.


Is there a solution to resolve this issue?

iPhone X, iOS 16
