Cannot deploy xamarin app to physical iOS device

I accidentally deleted Apple certificates necessary for the deployment of Xamarin app to iPhone SE2. I created new certificates, added them to KeyChain with Macin Cloud, created new provisioning profiles and everything seems to be working properly, but I am getting an error from VS Studio when deploying the app.

The error is caused by:
Unhandled Exception: Xamarin.iOS.Windows.WindowsiOSException: Failed to install the application: ApplicationVerificationFailed(3892346905) - Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.mDjJvM/extracted/Payload/TestAppName.iOS.app : 0xe8008019 (The application does not have a valid signature.)

I do have paid Apple Developer account and I am using Visual Studio 2019 16.9.5 on Windows 10. I tried cleaning/rebuilding the solution, creating new projects, deleting C:\Users\User\AppData\Local\Temp\Xamarin folder. I can see both; certificate and provisioning profiles in Tools>Options>Xamarin>Apple Account>"View Details" window, the certificate is valid and the profiles are new (not expired).

My guess is that I may need to use my private key in KeyChain to verify the certificate, but I can see the certificate under my private key already.

Full error message:

    Visual Studio 16.9.6 was just released. It fixes the issue.

    From the release page:

    Issues Addressed in this Release:
    Fixes "Cannot access a disposed object. Object name:'System.Net.Http.StringContent'" when trying to create a certificate or running Automatic Provisioning.
    We have fixed a problem that prevents the iOS Hot Restart feature to work correctly.

    Sorry to reopen this but I have the same issue

    I'm using Visual Studio 2019 - 16.11.5 on a Windows PC. I don't have a Mac but I have an iPhone (15.0.2). The Xamarin Forms version is 5.0.0.2125

    I already do the Bundle Signing as says failed-to-verify-code-signature-of-cant-install-application-on-my-iphone and automatic-provisioning

    One thing is that the account with an active membership is from my boss so I use their credentials to sync when VS asked for it, but the iPhone uses another credentials. Don't know if that matters

    On the second link says "This automatically checks to see if the device is registered on the Apple Developer Portal. If it isn't, it will add it and generate a new provisioning profile that contains it." But as I said, I don't have a Mac and I don't know if that applies to this

    The complete error is this:

    Deploy Error: Could not install the application '...path to App.iOS.ipa' on the device MY_IPHONE . Details: ApplicationVerificationFailed(3892346901) - Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.9J05nX/extracted/Payload/App.iOS.app : 0xe8008015 (A valid provisioning profile for this executable was not found.)

    @sunco there is an open issue for this (Hot Reload does not work on ios 15 for a locally connected device):
