Hello,
Thanks for contacting us and sorry for any inconvenience that might have been caused due to that.
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:

That should fix the issue. Please let me know if that does not. We are here to assist.
Thank you very much! Step 1 did the trick!
Hello,
Glad that helped. We will still recommend that you follow the second step and exclude the sitemap from being cached to avoid this issue in the future.
Please feel free to reach out to us again in case you need any other assistance.
We are here to help.
Thank you.
