Additional info: the issue only seems to happen when the screen is off/black (iPhone 7 and iPhone SE) and not when it is locked but on
Update: while the phone is connected to the power adapter, the problem does not exist... So something in iOS 15.8 prevents the VoIP app from being loaded completely while the screen is off and the phone is not connected to the power adapter.
According to the logs the code is stuck till the screen is turned on while executing applicationDidFinishLaunchingWithOptions (it goes further than our PushKit and CallKit initialization, but stops executing before delivering the VoIP Push notification).
