Would like to inform you that I switched to the sitemap.xml format as your sitemap was giving this error.
Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
Can you please follow these 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:

Once done, clear your website cache and resubmit the sitemap_index.xml
in the Search Console.
Hope this helps.
We look forward to helping you.
Thank you, the problem is resolved!
