wp question – WP_Query by meta key not returning any posts

I’ve set a customized meta key ‘post_views’ on a customized put up sort which I can see in my database has been added for 3 posts.

I now have to retrieve the ID’s for these posts by looking for all posts which have this meta key.

$q = new WP_Query([
    'meta_key'   => 'post_views',
]);

$posts = $q->posts;

foreach($posts as $put up) {
    var_dump($put up);
    echo $put up;
}

My downside is that once I do the WP_Query it doesn’t return any posts.

Can anybody see why im not getting any outcomes?

Thanks you

Additionally if I var_dump($q) it returns the next:
