I encountered the same issue but was able to resolve it. Please follow these steps:
Open Keychain Access on your Mac.
Locate your certificate and double-click it.
Navigate to the Trust section and set it to Always Trust.
Open Xcode and go to Signing & Certificates.
Click Try Again for the provisioning profile.
Run the app on your physical device.
Following these steps should resolve the issue.
