Displaying Data in Shordcode

I have been trying to figure out why

$cover_img = get_post_meta( $post->ID, 'dc_sermons_dc_cover_img', true );

Isn’t displaying in my shortcode loop. The shortcode is on the home page if that matters. Any ideas?

Here is my shortcode:

add_shortcode( 'sermon-hub', 'dc_simple_shortcode' );
function dc_simple_shortcode( $atts ) {
    ob_start();
    global $query;

    $query = new WP_Query( array(
        'post_type' => 'sermon_hub',
        'posts_per_page' => 3,
        'meta_key' => 'dc_sermons_dc_date',
        'orderby' => 'meta_value',
        'order' => 'DESC'
    ) );

    
    if ( $query->have_posts() ) { ?>
        <div class="dc-grid" style="width:100%; max-width:1020px; padding-top:25px;">
            <?php while ( $query->have_posts() ) : $query->the_post(); ?>
            <div class="dc-col-1-3 blurb-ripple-out" style="position:relative;">
                          <div class="dc-post-container" style="<?php
