Labels: Fuzz-Blocker ReleaseBlock-Beta M-69
This crash occurs very frequently on windows platform and is likely preventing the fuzzer phoglund_webrtc_peerconnection from making much progress. Fixing this will allow more bugs to be found.

Marking this bug as a blocker for next Beta release.

If this is incorrect, please add ClusterFuzz-Wrong label and remove the ReleaseBlock-Beta label.
