This has intermittently happened to me as well. Repro is not perfectly reproducible (the first time I wanted to generate logs, I couldn't reproduce with the same person that does generally crash me). However, today it did reproduce while running Fluxer from the command line.
Manjaro running the AppImage, see fastfetch output for high-level OS details. Log captured is:
[547632:0306/134722.216213:ERROR:third_party/webrtc/pc/sdp_offer_answer.cc:431] A BUNDLE group contains a codec collision for payload_type='111. All codecs must share the same type, encoding name, clock rate and parameters. (INVALID_PARAMETER)
