Eventbrite Participants cannot access without password

I run writing workshops via Zoom, which participants book and pay for through Eventbrite. In the past I had no trouble with participants accessing the Zoom meeting through the link they were sent once they had purchased their tickets on Eventbrite. A couple of weeks ago, I paused my Zoom subscription for a few weeks, and since I have started it up again, participants cannot access the Zoom meetings with the links that they receive in Eventbrite. It asks them for a password. The only way they can access a meeting is if I send them the meeting info link from within an already active meeting. As you can imagine, this causes complete chaos for me, with multiple emails to and fro whilst I am trying to host the space. Any ideas would be SO welcome!
