Zoom not responding and dropping meeting

[ZVision]

About 10 minutes into every Zoom meeting lately my screen freezes, goes gray, and says that Zoom is not responding.  Clients can hear me, but after 5 minutes of that Zoom drops me off the call and automatically puts me back in the call.  Nothing happens to the client except that they are talking and I miss part of the conversation.  This normally wouldn't be a problem except that I am a coach and it's critical to my business that I listen carefully to the entire conversation, not just pieces of it.  How can I stop this from happening?
