Custom Post Archive Not Displaying, Custom Posts Fine

I created a custom post type with a plugin. Below is the code

add_action( 'init', 'create_sjl_music' );
function create_sjl_music() {
    register_post_type( 'sjl_music',
        array(
            'labels' => array(
                'name' => 'Music',
            ),
            'public' => true,
			'description', 'Holds data for music files',
            'menu_position' => 5,
			'rewrite' => array('slug' => 'music'),
            'supports' => array( 'title' ),
            'taxonomies' => array( '' ),
			'has_archive' => true,
            'menu_icon' => plugins_url( 'images/sjl-music.png', __FILE__ )
        )
    );
}

(I use almost the exact same code for another custom post type and it doesn’t have this problem.)

The problem is that the individual posts will display correctly. Ex. https://de-blase.com/music/mustache-mix-002/

But the archive page (https://de-blase.com/music/) gives a 404 error.

I’m using this permalink structure:
https://de-blase.com/%category%/%postname%/

and i’ve flushed the permalinks twice.
