Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
I have checked your sitemap and it is working fine on my end.
It looks like Google is seeing a cached version of your sitemap.
Are you using Cloudflare?
If yes, please follow this guide:

Alternatively, you can try using any other caching plugin and see if the issue persists.
Looking forward to helping you.
