start mac zoom desktop, cannot join meeting, when I exit zoom I get a leave meeting message

Subject says it mostly:  I start zoom, I command-J to join a meeting and get a beep.  No meeting shows in the drop-down of open Windows.  I exit zoom and get a "leave meeting ?" query.  

No error codes.

Device type: Macbook - apple silicon - Sequoia 15.4.1

Zoom version: Version: 6.4.6 (53970)

Deleted, cleaned up after, and resinstalled OSX Zoom
