Sitemap is not created

Hi,

My domain is: https://spiritualawakeningway.com

My Sitemap is disappeared. (https://spiritualawakeningway.com/sitemap_index.xml) I had 3 different links there but now there’s no one. I am not sure what is happening, everything looks good.

Recently i was filling the Users page in WordPress (https://spiritualawakeningway.com/wp-admin/users.php) trying to optimize my SEO. I am not sure if this is related with my issue.

Can you provide me assistant with this?

Thank you so much.

Eduardo.
