Zoom email+calendar issues with Mac Big Sur

Hi folks

I've just switched from a Windows 10 laptop to a MacBook running Big Sur 11.2.3, and am now having problems when setting up meetings in Zoom in a pre-existing account. The Zoom account was running fine before I switched to the MacBook, and I've not changed any settings in either Zoom or Google Calendar.

In summary when I set up a meeting with other people in Zoom they are now not receiving my email invitations, even though the meeting - and the invitees - is showing as normal in my Google calendar. The invitation email doesn't show up in my Sent log either (it used to). When I hover my mouse over the 'meeting organiser' box in Google I can see the correct email address for my Google calendar but my name is not shown, instead it says 'VPN + 3 letters + special character'. I don't understand why, as I'm not using a VPN and i've not changed any Google Calendar settings.

I've tried to see if the problem is resolved by turning the Mac firewall off & on, but it makes no difference.

Has anyone any ideas what this issue is, and how I an resolve it? It's a huge pain as I'm now having to manually send the Zoom meeting links to every invitee!
