Getting Error in Semrush for 800 incorrect pages found in sitemap.xml [Please HELP]

I am getting an error in Semrush for 800 incorrect pages found in the sitemap.xml related to non-canonical URL's. But I don't know how to fix this issue as I tried Yoast SEO Premium, Yoast SEO Test but is there anyway how to fix it.

I dont want to Disallow in robot.txt

Please help

Well check the sitemap first. See if the bad URLs are really there or not. If there are bad pages it means that the sitemap was created badly, and you should have it remade.

Open gsc check there first, move on from yoast to the seo framework, if no errors in gsc then relax
