Got Error post meta table exceeds the size limit.

Hello,

Thanks for contacting us, and sorry for any inconvenience that might have been caused due to that.

Please trying adding the following filter to your site in order to fix this issue:

/**
 * Filter to change the Post Meta Table Limit
 */
add_filter('rank_math/seo_analysis/postmeta_table_limit', function ( $limit ) {
		return 500000;
	}
);

And here is how to add a filter/hook to your site: https://rankmath.com/kb/wordpress-hooks-actions-filters/

Let us know how it goes. Looking forward to helping you.

Thank you.
