Zoom One Pro desktop app on my MAC no longer working to schedule meetings

Starting about two weeks ago, when I click on the Schedule icon it opens to a new screen that is not working. Per screenshot attached, it's missing most of the dialogue options. I fill out as able, hit “save” and a dial spins & spins and then I get the error message attached. I can't schedule a Zoom call.  Note that I've already tried removing and then reinstalling the Zoom app but problem remains. Zoom tech support has been non-responsive. Need Help. Thanks!
