Secondary registration window after clicking Join Meeting

After the latest update, we are now seeing a secondary registration to the right of the main Zoom window where the user is asked for their name and email (even though we are passing this in the normal code)

How do we stop this ?

@cogora ,
Thank you for posting in the Zoom Developer Forum! Could you please provide a screenshot of your join and init functions? Additionally, could you specify the meeting settings that have been configured, such as Meeting registration or Meeting authentication?
