Hello,
Thank you for contacting us and we regret the inconvenience caused.
Please follow the below steps:
1. Flush the Sitemap cache by following this video screencast:

2. Exclude the Sitemap files of the Rank Math plugin in your caching plugin. The cache could be via a plugin or from the server. For plugins or Cloudflare, please follow this article:

3. Clear your website’s cache and remove all the sitemaps from your Google Search Console account, and then submit only the main sitemap (your-domin.com/sitemap_index.xml) (please ensure to replace “your-domain.com” with your actual domain).
Further, give Google some time to crawl your website again and see if the issue is fixed.
Hope that helps.
Thank you.
