Stuck at Join A Meeting

[cshih3]

This weekend my ZOOM Client started showing a new problem:

I use WINDOWS 10 PRO OS on two laptops and have the same symptom. 

When signing in to my account and opening ZOOM Client, I clicked Join Meeting but the client returned to the Join Meeting prompt. I then uninstalled ZOOM 5.15.5, re-booted, and re-installed ZOOM Client. No success.

I am forced to join the meeting via browser Chrome.

Did anyone encounter this new issue? Is it a ZOOM Client problem?  Please help.
