Canonical Tag, Noindex tag, Crawled Problems, Robot Txt, Unknown Pages Redirect

this is related to the “Alternative page with proper canonical tag” problem
my google console is showing this problem. My page’s URLs are set with slashes via WordPress’s permalink settings(/%postname%/). The pages shown in my google console are shown without slashes and there are no such URLs in my sitemaps either. So tell me why such a problem is coming and why Google is crawling such URLs which is not on my sitemap. please fix this issue.

Excluded by ‘noindex’ tag Problem
I have set some pages to noindex using rankmath & I have not included the tags in the sitemap but still, Google is trying to crawl them and it is showing an error. I have not allowed it, so why is this error coming?

Problem – “Crawled – currently not indexed”
Google is crawling URLs of pages that are not in my sitemap. I saw in google console that the URLs of my pages were showing very long, but I have not created such permalinks. I saw in google console that my pages were getting different variants of URLs and getting crawled. Then this problem is coming, why is it coming?

Problem – Blocked by robots.txt
I have blocked the pages even then how is google trying to crawl?

Problem – Page with redirect
There are no such pages in my sitemap that are visible in the console. How can the problem of redirecting come to them, where did such pages come from?

I have attached screenshots of all these problems below.
