Black Screen of Death (ClassNames is not defined)

I’m encountering a serious production issue with the Web Client SDK during a Webinar we’re running. Participants of a meeting are getting kicked out with a black screen.

Web Client SDK 1.9.5

With the errors

cancelConsume interval 3 requestId null
destroy SDK
ReferenceError: ClassNames is not defined"

edit: happened on receive of this data packet
{"body":{"activeNodeID":33555456,"bStatus":0,"ssrc":0},"evt":20225,"seq":260}

I want to add that when this happens, it appears to knock off a significant portion of participants at the same time.

Just to correct myself, it was a meeting. I’ve sent an email out with the meeting Id. Thanks Max.
