Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience casued.
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.
