I am using Xcode Version 15.3 (15E204a) and different versions of Simulator runtimes (17.x, 16.x, 15.0)
The app makes outgoing calls and can respond to incoming calls. After starting the call, ~2s pass before a hangup occurs. In the Console logs I see that CXEndCallAction was invoked by CallKit and the last suspicious log before invoking the CXEndCallAction is
callservicesd Disconnecting call because there wont be a UI to host the call: <CSDProviderCall 0x107054300 type=PhoneNumber, value=sdsddsdds, stat=Sending tStat=0, model=<TUCallModel 0x103f661e0 hold=1 grp=1 ungrp=1> ...
This used to work before, but since upgrading to Xcode 15 and iOS 17.x it happens constantly on simulator versions 17.x, and sometimes on 16.x, whereas I wasn't able to reproduce it on 15.0 version.
Can someone help me understand why this happens and how to fix it? I provided some logs down below, and I don't see similar logs in the cases when the call is okay and CallKit doesn't hangup it.
Also, this does not happen on real devices
From the time CXStartCallAction is invoked until the CallKit invokes CXEndCallAction, these are some of the error or warn logs that appear:
callservicesd -AVSystemController- +[AVSystemController sharedInstance]: Failed to allocate AVSystemController, numberOfAttempts=3
callservicesd [WARN] +[AVSystemController sharedAVSystemController] returned nil value

The logs provided are in order in which they are logged, but some of them are recurring After these logs there is still a message that CXStartCallAction is fullfilled:
callservicesd Start call action fulfilled: <CXStartCallAction 0x107231fe0 UUID=8D34853F-55DD-4DEC-97A7-551BFD27C924 ...>
After which the last suspicious log is logged before CXEndCallAction is invoked by CallKit:
Disconnecting call because there wont be a UI to host the call: <CSDProviderCall 0x107054300 ...>
