Visual Studio raises an error MT1045 Failed to execute when deploy a MAUI app to a real device

I have my .NET8 MAUI application and I try to test it on my physical iPhone. Visual Studio 17.8.7 is connected to my iMac and the iPhone to the iMac. The deployment on Simulator is working fine. When I deploy on the iPhone, Visual Sutdio shows this error

error MT1045: Failed to execute 'devicectl': 'devicectl -j /var/folders/dm/bwmxpbzn6bvdsyy73c_b453w0000gn/T/tmpBkAavG.tmp device install app --device "Enrico???s iPhone" /Users/enrico/Library/Caches/Xamarin/mtbs/builds/LanguageInUse/1fa03704bb15e35c6f47a701d9d92131e3e0740198296a93338bb3c829bc9cf7/bin/Debug/net8.0-ios/ios-arm64/device-builds/iphone15.2-17.3.1/' returned the exit code 1. In the Output window, I also notice this error:

NSLocalizedFailureReason = This app cannot be installed because its integrity could not be verified. NSLocalizedRecoverySuggestion = Failed to install embedded profile for : 0xe800801f (Attempted to install a Beta profile without the proper entitlement.)

I like to highlight that I deployed the application on the iPhone roughly a month ago without issues. I got the Provisioning Profile from the Apple Store and so on.

The configuration on Visual Studio for iOS is the following.

    From the screenshot, you selected the distribute provisioning profile which is for release and AppStore, but you should select a development provisioning profile.

    If you have the profile, you could select it. If not, please follow the steps to create development provisioning profile in the doc - Manual provisioning for .NET MAUI iOS apps - .NET MAUI | Microsoft Learn, then download the development provisioning profiles and use it.

    (Pay attention to adding your device)

    Best Regards,
