How to redirect all internal Wordpress pages except for the admin panel to the main one?

Question

htaccess

I want to make a landing using WordPress, but each post also has a separate page at its site.ru/archives/90 address. I need all internal pages to redirect to the main page. But! There is a path to the admin panel /wp-admin/, a redirect is not needed on this folder for the admin panel to work. thanks for the help
