Custom Post Type Single Page is not working

I wanted to know, why my single custom post type isn't working.

Everytime I wanted to open the single post type it automatically gets back to the homepage.

Please help!

Here is my code:

// Team im Backend hinzufügen

function register_team() {
    $labels = array(
        'name' = __( 'Team', 'team' ),
        'singular_name' = __( 'Team', 'team' ),
        'add_new' = __( 'Neues Mitglied', 'team' ),
        'add_new_item' = __( 'Neues Mitglied', 'team' ),
        'edit_item' = __( 'Mitglied bearbeiten', 'team' ),
        'new_item' = __( 'Neues Mitglied', 'team' ),
        'view_item' = __( 'Zeige Mitglied', 'team' ),
        'all_items' = 'Alle Mitglieder',
        'search_items' = __( 'Suche Mitglied', 'team' ),
        'not_found' = __( 'Keine Mitglied gefunden', 'team' ),
        'not_found_in_trash' = __( 'Kein Mitglied im Papierkorb gefunden', 'team' ),
        'parent_item_colon' = __( 'Übergeordnetes Mitglied:', 'team' ),
        'menu_name' = __( 'Team', 'team' ),
        'public' = true,
        
        
    );
    $rewrite = array(
        'slug' = 'team',
        //'slug' = 'portfolio',
        'with_front' = true,
        'pages' = true,
        'feeds' = true,
    );
    $args = array(
        'labels' = $labels,
        'supports' = array( 'title', 'editor', 'excerpt', 'thumbnail', 'comments', 'trackbacks', ),
        //'taxonomies' = array( 'category' ),
        'hierarchical' = false,
        'public' = true,
        'show_ui' = true,
        'show_in_menu' = true,
        'show_in_nav_menus' = true,
        'show_in_admin_bar' = true,
        'menu_position' = 5,
        'can_export' = false,
        'has_archive' = true,
        'exclude_from_search' = false,
        'publicly_queryable' = true,
        'rewrite' = $rewrite,
        'capability_type' = 'page', 'post'
    );
    
    //register_post_type( 'products', $args );
    register_post_type( 'team', $args );
}
add_action( 'init', 'register_team' );


// Custom Taxonomie für Team hinzufügen (wie Kategorien)
function add_team_taxonomies() {
  register_taxonomy('teamtaxo', 'team', array(
    // Hierarchical taxonomy (like categories)
    'hierarchical' = true,
    // This array of options controls the labels displayed in the WordPress Admin UI
    'labels' = array(
      'name' = _x( 'Team Kategorie', 'taxonomy general name' ),
      'singular_name' = _x( 'Team Kategorie', 'taxonomy singular name' ),
      'search_items' =  __( 'Search Kategorie' ),
      'all_items' = __( 'All Kategorie' ),
      'parent_item' = __( 'Parent Kategorie' ),
      'parent_item_colon' = __( 'Parent Kategorie:' ),
      'edit_item' = __( 'Edit Kategorie' ),
      'update_item' = __( 'Update Kategorie' ),
      'add_new_item' = __( 'Add New Kategorie' ),
      'new_item_name' = __( 'New Kategorie Name' ),
      'menu_name' = __( 'Team Kategorie' ),
    ),
    // Control the slugs used for this taxonomy
    'rewrite' = array(
      'slug' = 'team', // This controls the base slug that will display before each term
      'with_front' = false, // Don't display the category base before /locations/
      'hierarchical' = true // This will allow URL's like /locations/boston/cambridge/
    ),
  ));
}
add_action( 'init', 'add_team_taxonomies', 0 );

This is my team category site:

And I can't click on 'mehr lesen...' without getting back to my homepage?

Thank you!
