WordPress custom post type rewrite resolve 404 error on pages and articles

Question

I have a problem that I can't solve. Thanks to anyone who can help me.

My goal is to remove the custom post type name from the URL and insert the associated taxonomy term name in its place. Also, the taxonomy name must not appear in the URL.

first -> mysite/custom-post-type/tax-term/single-custom-post-type

correct -> mysite/tax-term/single-custom-post-type

I was able to do this without too much trouble and the taxonomy term store works too. The problem is that the site's pages and posts are now returning a 404 error.

If I set the permalink structure to plain everything works, but this is not SEO friendly.

here is my code.

        // Other labels...
