Zoom becomes unresponsive after I join a meeting on MacBook

[mvhall]

I join a meeting on my MacBook, then zoom becomes unresponsive. I cannot click on anything (Unmute button/camera/chat/minimise screen etc) However, I can see everyone, and hear everything but I cannot do anything from my end. I have looked through the settings, restarted my computer a number of times, updated what needed to be updated. Still, the problem persists. Can anyone help?
