zoom freezing

I'm having a similar problem, though my freezing generally occurs when I'm put into a breakout room.  I get a "cannot detect microphone", then a "Zoom not responding" message, even though I have done absolutely nothing.  I've just posted about this issue, and am hoping someone will have some suggestions and/or solutions.

I'm having a similar issue also. I get into the zoom meeting fine. But when I click to close the mic or camera it will freeze and the zoom facilitator cannot even shut me off. So I have to sign out and come back in. It doesn't happen every time. It is random but happens often enough to  be very annoying. I've sent my laptop in for a complete tune up and cleared things that would use a lot of bandwidth but still no resolution. 

Well I am not saying this is the answer BUT if I have more than one application running while I am conducting a Zoom meeting, my computer's internal memory has trouble handling all the application running at the same time. Try and close all applications except the ones you want to use to share with your group to help with memory freeze issues. Hope this helps.

I was having the same problems. Very slow to start the desktop client. Slow to connect (the first time) and occasional "not responding" messages. I first disabled Bitdefender, but the problems kept occurring. Once I uninstalled Bitdefender completely and reverted back to Windows Defender, everything worked ok. It looks like Bitdefender and Zoom are incompatible.

Still having freezing issues.  MS update is fixed.  Had 4 tuneups every week for the last month.  Reinstalled zoom 4 times.  Still having issues opening and staying usable - before and during meetings.

Zoom won't respond to my last email back and forth with escalation because they say case is closed.  Now they won't answer my call.  HELP please.
