I got exactly the same error when deploying app to my iPhone (running on iOS 14.1)

We are facing this issue too. The reason is that your device doesn’t recognize the provisioning profile even it has been created and attached to your ipa file correctly. The workaround I found is to archive the app and generate an ipa file for distribution first, install it to device. With that step, your device has checked and confirmed the app’s integrity.  Hope that helps, JayZ

Same here. @Environment(.dismiss) and NavigationLink don't work together.
