Anyone have this issue using Zoom on a Mac?

My Zoom client stopped working on my Mac. I've followed all the Google trouble shooting sites and YouTube videos, and I'm still unable to connect. I've also un-install the Zoom client, updated my Mac's operating software, did a full restart, re-installed the Zoom Client, and made all necessary firewall and security modifications, changed my Zoom password, and made sure Zoom can access the mic and camera, etc. However, I'm still unable to sign in on my Mac. Any suggestions would help. Thank you!
