Error al crear la version

Testflight error message: "Could not install app. Your request couldn't be completed. Try again." I have tried installing TestFlight builds 7 times with different apps, but none have been installed. I have the latest TestFlight updates, so that is not an issue. I also referred to this link too to troubleshoot this: https://developer.apple.com/forums/thread/701330 I have not had any other issues with deploying the app. Can Apple fix this so we can install the TestFlight build?

Every time I try to update my newest sticker pack in Xcode, It gives me this error "warning: The CFBundleShortVersionString of an app extension ('1.2') must match that of its containing parent app ('1.0')."
