The same for me. When I try to connect to the meeting it still shows the error, but immediately replaced by the new window and connects fine

Are the web version works fine for you? In chrome it connects, sound works fine, but I can't see videos and screen sharing(((

Thanks for your support, Cole. The versions are the same as you mentioned. What is TAC and how can we contact them?    

I've also removed all the related to cisco/webex content from `~/Library/Caches` and `~/Library/Application Support`, restart the app,  login, and still can't join or create a meeting.  @Nithin Eluvathingal, yes M1 chip. 

What kind of cache do you mean? And what is the best way to clear it?  P.S. I'm using the desktop app
