iOS 26 Voip + LiveCommunicationKit device is unlocked not work

After upgrading to iOS 26, the video call feature previously implemented using Voip + LiveCommunicationKit is behaving inconsistently: when the device has a passcode, the app can properly launch to the call screen, but when there's no passcode and the device is unlocked, the app fails to launch and enter the call page. How should this issue be resolved?
