Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
You have the global noindex robots meta enabled for your site via Rank Math > Titles & Meta > Global meta as shown below:
This is the cause of the issue, I have disabled this option for now and the sitemap is now working correctly.
Looking forward to helping you. Thank you.
