Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
Please try following the steps below to see if that works for you:
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.
Let us know how it goes. Looking forward to helping you.
Thank you.
I did all the steps. But it was not resolved
Hello,
Please get in touch with your hosting provider and ask them to check if there’s something blocking Googlebot from crawling your sitemap.
Also, if you’re using any security plugin or firewall for your site, make sure they are not blocking Googlebot.

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