This issue typically occurs due to cache. Please, flush your site-specific cache and server level cache. Once you clear the cache correctly, please resubmit the sitemap to Google search console property and which should resolve this issue.
Notice that once you resubmit the sitemap, it may take a little while to see the updated changes. So, we recommend you to please wait at least 24 hours after resubmitting the sitemap.
Hello
What you said did, but it still has a problem. Previous links that contain the category when indexed again gives 404 error. The URL does not work at all. Google has issued this warning.

When we tested a sample of the URLs from your Sitemap, we found that some URLs were not accessible to Googlebot due to an HTTP status error. All accessible URLs will still be submitted.
Can you please show us some example URLs that you find in the XML Sitemap and shows HTTP error?
All the links in
http://3dspro.ir/category-sitemap.xml
They have the same problem. Just add /category/ them to the beginning:
http://3dspro.ir/category/پلاگین-نرم-افزارها/پلاگین-مایا/
The redirects are not executed correctly and give the error address 404. Because the Google Index has already indexed its index again, it returns an error of 404 when it re-indexes.
Unfortunately, we think the issue is specific to your site. We’d need to investigate further but are unable to do so on these forums. You can purchase Yoast SEO Premium and receive our Premium email support and we can help you further.
