Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
For initial troubleshooting, you can try to follow this guideline and see if that works for you: https://rankmath.com/kb/delete-old-analytics-data/
If the issue still persists, please follow the steps below to create a troubleshooting log so that we can check the issue further for you.
1. At first add the following filter to your website:
add_filter( 'rank_math/analytics/log_response', '__return_true' );
Here is a guide you can follow to add the filter:
https://rankmath.com/kb/wordpress-hooks-actions-filters/
2. After adding the filter, please run the pending Scheduled Action from your 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
This is how it should look like:

When some actions have completed running, please check the Analytics log under wp-content/uploads/rank-math
and share that with us. You can upload the log file using this tool.
Looking forward to helping you.
Thank you.

Best regards,
