Unable to get goToWebinar to work in Safari

If I go to the test meeting (without an account) I get

’Do you want to allow this page to open “GoTo Opener”
I hit allow - nothing happens
Also on that page is a ‘download the app’ - but this is the same opener as before
I end up with the goto opener app running, but a bouncing icon in the dock

Maybe this is ventura specific, but we are pretty late in the cycle now, and I’ve had no issues with Zoom, Cisco WebEx, Microsoft teams, Google meet

Note that the ‘goto opener’ if opened and double clicked, also just gives the bouncing icon - nothing more happening. (I dragged to applications as it wasn’t clear what to do)
