For what it is worth? I don’t think X-Robots-Tag: noindex; is benign (as I believe I’ve read elsewhere). Seemed to be to be the exact problem, as Google told me it was. In my case? It was apparently being added by the SEO plugin (The SEO Framework), which was auto-generating the sitemap. Because my site –– the-Circles.Club –– has a simple structure, I put a plain sitemap.xml file in WP home, turned off Sitemap Generation in the plugin, and that fixed it. As has been reported, you should be able to see all you need to see in the Chrome inspector; no need to bother Google every time … ??
