Crash app when create peer connection

[chimjk]

Hi,
I tried upgrading the application to Qt6. However, when running the application, it crashes when creating PeerConnection.

line 438: RTCSDK/plugin_client.cpp
context->pc = _pluginContext->pcf->CreatePeerConnection(pcConfig, nullptr, nullptr, static_cast<webrtc::PeerConnectionObserver*>(this));

Is webrtc buggy or do I need to provide any additional libraries?

Thanks.
Hung
