Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
I checked your sitemap, and it seems to be working and validating fine.
However, Rank Math generates the sitemap in this format (/sitemap_index.xml) which is missing in your robots.txt file.
Here is the recommended guide to use in robots.txt:

After that, remove all your submitted sitemaps and resubmit your main sitemap (/sitemap_index.xml) only.
Once done, clear your website’s, server (if any) cache and wait for Google to crawl it again.
Looking forward to helping you.
