Zoom keeps freezing.

[pol62]

Since I subscribed to Zoom Pro my meetings freeze after about 90 minutes.
First my video freezes but I can hear the meeting and the other participants can hear me but I cannot access chat or raise my hand or do anything except listen and talk. After a few minutes I cannot be heard by the other participants and I have to restart my computer and re-enter the meeting.
I have removed the zoom program and re-installed but it has made no difference.
