How to remove the Custom Post Type slug name from the url, without creating issue to previous posts or pages?

I've tried the following solutions: https://wordpress.stackexchange.com/a/204210 - 404 page https://kellenmace.com/remove-custom-post-type-slug-from-permalinks/ - 404 page http://www.codeinhouse.com/remove-slug-from-custom-post-type-in-wordpress/ - 404 page

Answer 1

Change permstruct for your CPT.

add_action( 'init', function() {
    add_permastruct( 'tvshow', '/custom_home_page/%tvshow%');
}, 11);

However, this is a complex question and can involve different steps to make it work in different ways.

P/S/ don't forget to flush url rules.
