Zoom failed to start recording locally

I just ran a Webinar and configured it to 'Automatically start recording when session starts'. The recording was set to local.

I discovered after the webinar that there was NO recording. It hadn't started.

Am I a complete idiot or did Zoom fail? Now I have to record it again because many people didn't join but were offered the recording. This is NOT fun.

Thank you for any ideas!
