Disable search for custom post type

Hi,

I have some problems I hope you can help.

I used the function below to create the CPT video:

function mefvideos_init() {
    // set up video labels
    $labels = array(
        'name' => 'Vídeos',
        'singular_name' => 'Vídeo',
        'add_new' => 'Adicionar novo',
        'add_new_item' => 'Adicionar novo',
        'edit_item' => 'Editar vídeo',
        'new_item' => 'Novo vídeo',
        'all_items' => 'Todos os vídeos',
        'view_item' => 'Ver vídeo',
        'search_items' => 'Buscar vídeos',
        'not_found' =>  'Nenhum vídeo encontrado',
        'not_found_in_trash' => 'Nenhum vídeo na lixeira', 
        'parent_item_colon' => '',
        'menu_name' => 'Vídeos',
    );
    
    // register post type
    $args = array(
        'labels' => $labels,
        'public' => true,
        'has_archive' => true,
        'taxonomies' => array( 'videos_category' ),
        'show_ui' => true,
        'capability_type' => 'post',
        'hierarchical' => false,
        'exclude_from_search' => true,
        'rewrite' => array('slug' => 'video', 'with_front' => FALSE),
        'query_var' => true,
        'menu_icon' => 'dashicons-video-alt3',
        'show_in_rest' => true, // To use Gutenberg editor.
        'supports' => array(
            'title',
            'editor',
            'excerpt',
            'trackbacks',
            'custom-fields',
            'comments',
            'revisions',
            'thumbnail',
            'author',
            'page-attributes'
        )
    );
    register_post_type( 'videos', $args );
    
    // register taxonomy
    register_taxonomy('videos_category', 'videos', array('with_front' => true, 'hierarchical' => true, 'label' => 'Categorias vídeos', 'show_in_rest' => true, 'query_var' => true, 'rewrite' => array( 'slug' => 'videos' )));
}
add_action( 'init', 'mefvideos_init' );

I used this other function so that any page, post, tag or category created would not cause problems with the CPT "video":

dd_filter( 'wp_unique_post_slug_is_bad_hierarchical_slug', 'fe_prevent_slug_conflict', 10, 4 );
add_filter( 'wp_unique_post_slug_is_bad_flat_slug', 'fe_prevent_slug_conflict', 10, 3 );
function fe_prevent_slug_conflict( $is_bad_slug, $slug, $post_type, $post_parent_id = 0 ) {

	$reserved_top_level_slugs = apply_filters(
		'fe_reserved_top_level_slugs',
		array('videos',)
	);

	if (
		// Only check top level post slugs (i.e. not child posts).
		0 === $post_parent_id
		&& in_array( $slug, $reserved_top_level_slugs )
	) {
		$is_bad_slug = true;
	}
	return $is_bad_slug;
}

And finally, I used this function to enable the creation of categories for the CPT:

function wckc_add_my_custom_post_type ($query) {
    if(
        empty($query->query['post_type'])
        or $query->query['post_type'] === 'post'
    ){
        $query->set('post_type', array('post', 'page', 'videos'));
    }
}

add_action('pre_get_posts', 'wckc_add_my_custom_post_type');

This is my CPT https://bit.ly/31mL9JQ main page, this is a single page https://bit.ly/3zjpf6B and this is a category page https://bit.ly/31knwSb

Problems:

1) CPT are displaying in the search results, and would not like to enable them. Even because I used the parameter 'exclude_from_search' => true and with that they shouldn't be listed in the search.

2) In Wordpress I can no longer do any search for posts because when I try I get the message "Invalid Post Type" https://bit.ly/3EPAWmS

Thanks
