Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
I added your sitemap to be excluded from caching by your cache plugin on your site then resaved sitemap settings which seems to have fixed the issue.
I also validated the URL with this tool: https://www.xml-sitemaps.com/validate-xml-sitemap.html and it is valid from my end, here is a screenshot: https://i.rankmath.com/yvhXL3
Please check and let us know
Looking forward to helping you. Thank you.
