Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Your sitemap appears to be cached on your site. If you have a caching plugin, please exclude your sitemap URLs from caching and clear your site cache.
Once done you can then validate your sitemap URL here: https://www.xml-sitemaps.com/validate-xml-sitemap.html and if valid head to your GSC and resubmit only your main sitemap URL(sitemap_index.xml)
Looking forward to helping you. Thank you.
