As comparison, when the 'Wemeet' app stop it's broadcast upload extension, it raraly cause this problem.I compared the console log when 'Wemeet' stop it's broadcast extension and the log my app stop it's broadcast extension.I found this line is different: Wemeet: mediaserverd MEDeviceStreamClient.cpp:429 AQME Default-InputOutput: client stopping: <ZenAQIONodeClient@0x1080f7a40, sid:0x3456e, replayd(30213), 'prim'>; running count now 0 My app: mediaserverd MEDeviceStreamClient.cpp:429 AQME Default-InputOutput: client stopping: <ZenAQIONodeClient@0x107e869a0, sid:0x3464b, replayd(30232), 'prim'>; running count now 3 As we can see, the 'running count' is different.

This problem occured on Xcode latest version (13.4), and never occured on older version Xcode.

__ZN3rtc18webrtc_checks_impl8FatalLogEPKciS2_PKNS0_12CheckArgTypeEz can be parsed by 'c++filt' util to: rtc::webrtc_checks_impl::FatalLog(char const*, int, char const*, rtc::webrtc_checks_impl::CheckArgType const*, ...)

I finally solved my problem with 'xcframework'.I combined 'arm64' framework and 'x86_64' framework into a 'xcframework', and use the xcframework in my project, the problem solved.

I met this problem also.I can rebuilt the third party framework to 2 frameworks with ios and ios simulator architecture respectively.So, now my problem is how to add framework for ios and ios simulator building separately?
