Broken Internal Links After Update Permalink

I have a big problem with the internal links in the blog. It happened after you changed the permalinks,

From: my old permalink: %category%/%postname%.html

to: my new permalink: /%post_id%/%postname%.html


old links in my blog: mywebsite[.]com/articles/my-name-is.html
new links in my blog: mywebsite[.]com/516516/my-name-is.html

516516= /%post_id%


Therefore, all internal links "in text" are directed to page 404

Note: Everything is good, except links within articles, such as:


Now, How I can change all links to the new shape?

 

Can you check if the .htaccess has the default Wordpress code placed or not
