This happens about once a week, and it started about two months ago. 

System: MS Surface notebook + Windows 10 + latest updates (Windows and Zoom) installed.

What happens: I start Zoom meeting and share my screen. I am alone in the session, waiting for participants to show up. Nobody is has yet joined. 

Suddenly, the screen freezes and both the keyboard and the mouse are frozen. That may last for up to 10 minutes.

Then as suddenly, it unfreezes and "catches up". I mean that I can see all the mouse movements and keyboard strikes I typed while it was frozen  passing very quickly. Once, I was running a video when it froze, and the video ran very quickly when it unfroze.  After it has "caught up", things run normally.

Observation: It has not happened after people have joined the meeting, but it does not give me a warm feeling.

So far, I have reinstalled Zoom and I have disabled Hardware Acceleration.

Anyone seeing that problem?

A while back I signed up for a personal Zoom account. I used it mainly for online open mics where musicians perform for other musicians in an open mic fashion. Then I got a job and, of course, they had a work Zoom account for me to use. I'm on Ubuntu 21.10 so I downloaded and installed the zoom client. I get scheduled for Zoom meetings and I click on the link and a browser tab opens and starts the Zoom client. Sometimes I seem to be using my personal account and sometimes I am using my work account. And sometimes I have two zoom icons in my notification area and I am apparently running two different copies of Zoom. It's very confusing.

If I log out and stop all zooms and start one up again and click Sign In there's an SSO button there. Assuming that's single sign-on so I click that.  The Zoom window changes to say "Sign in with SSO" and then there is a domain <company name>.zoom.us. At the same time, there's another Zoom window that shows me logged in already with my work account.  Also, a browser tab opens also saying "Sign in with SSO" and has a Launch Zoom button. Finally, there are not one but two icons in my notification area for two different zoom apps running!

Clicking on the Zoom icons in my notification area yields two different menus. One Zoom icon lists:

Join Meeting...

Share Screen...

Switch Languages >

About

Exit

While the other one shows:

Join Meeting...

Share Screen...

Open Zoom

Settings

Switch Languages >

About

Log out

Exit

Looking at the process table I see not 1, not 2 but 4 zoom processes. Two of them are /usr/bin/zoom and two are /opt/zoom/zoom. /usr/bin/zoom is a symlink to /opt/zoom/ZoomLauncher. Seem that running /usr/bin/zoom (really ZoomLauncher) simply turns around and starts /opt/zoom/zoom, but then it just hangs around...

Considering I already have 4 zoom processes running with two windows and two icons in the notification area pressing "Launch Zoom"  in the browser tab seems pointless and indeed is pointless because clicking it does nothing.

Clicking on the short menu Zoom icon and selecting quit kills the Zoom window that had the "Sign in with SSO" leaving only two zoom processes. Closing the Launch Zoom tab does nothing but close that tab.

Is this really how Zoom is supposed to operate when you have personal and work Zoom accounts?

I'm on a new Mac and can't screen share. Yes, I've checked settings and it should work, but when I go to share, all I see is blank boxes, basically, with generic titles. When I double click, it tells me to open system preferences, but then won't. I can go to preferences another way, but not when I'm trying to screen share.
