On Dynamic Posts, if you are using the pagination in the Query Type "Dynamic - Current Query", the number of results per page should match the value you set in WordPress "Settings > Reading > Blog pages show at most".

Note: In the case of Woocommerce Products, navigate to Customizer > Woocommerce > Product Catalog, and make sure the multiple of rows per page and products per row equals the products you want to show per page.

If the values are mismatched, you can encounter to see a 404 error.
