Hi @roosites
You are facing sitemap couldn’t be fetched from Google Search Console.
What happens when you try to visit the sitemap manually from WordPress dashboard > Yoast SEO > Settings > General > Site features > XML sitemap and click on “view the XML sitemap”. Do you see the sitemap loads correctly?
If yes, kindly try to delete the sitemaps you have submitted in Google Search Console and only submit the index sitemap. Deleting the sitemaps will not hurt your SEO. So make sure you resubmit the index sitemap only and not the individual sitemaps [page-sitemap.xml, category-sitemap.xml]
Please know that Google Search Console is not real time. Crawling can take anywhere from a few days to a few weeks. Be patient and monitor progress using either the Index Status report or the URL Inspection tool.
