EOS Webcam Utility Pro only shows bar that says it's running and that's it

[DaveBr2]

So I installed v 2.3 for Mac.  When I start the EOS Webcam Utility Pro I do not get a window, only the top bar on the screen says it's running.  Nothing else.  No picture, no nothing.  And I can't close it without a force quit.  So need to force quit even to reboot the computer.  MacBook Pro with an M3 Pro chip.  MacOS 15.0.1.

Thanks for any help on this...
