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

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.
