I am unclear about what you are getting here

the_field('category_icon', $qv->ID);

I ask because the field name is category_icon. Is this a field that is added to a post or a category?

The field is added to a custom taxonomy. Every post will have only one custom taxonomy term applied to it but there are a few options of custom taxonomy that would be applied based on the post type.

You need to get the terms of the post which will return an array (even if there is only one). The you need to get the field from the term.

$terms = wp_get_object_terms($qv->ID, 'TAX NAME');
the_field('category_icon', $terms[0];
