Zoom continually restarts after upgrade

[MikeDiggins]

This morning, I updated to V6.1.6 (on Windows machine running current version of Windows). After about 20 minutes, Zoom started continuously restarting with an uptime of around 30 seconds. Switched the host to another machine connected to the same router but not updated, and the connection was stable, with no latency during a 10 minute conversation. While the restarts were happening, other participants on machines that had not been updated continued as normal. 
After that meeting, I started the client to do some testing, noticed that both the Join and Share buttons were greyed out. Another other reports of issues with this upgrade, please? Restarting Windows to see if there is anything there that might be causing this.
