Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
Could you please share your sitemap URL with us so that we can check the issue further for you?
Meanwhile, please try to follow the steps below and 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:
https://rankmath.com/kb/exclude-sitemaps-from-caching/
Once done, clear your website cache, remove all the submitted sitemap, and resubmit only the /sitemap_index.xml in the Search Console.
Let us know how it goes. Looking forward to helping you.
