Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
If you want, you can disable the Email Reports from WP Dashboard > Rank Math > General Settings > Analytics:

However, can you please confirm if the data is available on your Rank Math Analytics Dashboard? If so, you can trigger the email report by visiting the following URL (update the link with the actual domain name).
https://yourdomain.com/?rank_math_analytics_report_preview=1&send=1
Once you’ve received the email, please head over to WordPress dashboard > Tools > Scheduled Actions > Pending.
or you can try visiting the following URL:
https://yourdomain.com/wp-admin/tools.php?page=action-scheduler&status=pending
Run the rank_math/analytics/email_report_event scheduled action,
This is how it should look like:
This will force the site to send an Analytics report to the desired email address.
After that, observe if the issue persists in the next schedule.
Let us know how it goes. Looking forward to helping you.
