Here is the complete working way to make "COD" payment method disable a specific shipping method.

You will have to set in the first function the shipping method Id that you wish to hide.

The code:

add_action( 'woocommerce_package_rates','show_hide_shipping_methods', 10, 2 );
function show_hide_shipping_methods( $rates, $package ) {
    // HERE Define your targeted shipping method ID
    $payment_method        = 'cod';

    $chosen_payment_method = WC()->session->get('chosen_payment_method');

    if( $payment_method == $chosen_payment_method ){
        unset($rates['flat_rate:12']);
    }
    return $rates;
}

add_action( 'woocommerce_review_order_before_payment', 'payment_methods_trigger_update_checkout' );
function payment_methods_trigger_update_checkout(){
    // jQuery code
    ?>
    <script type="text/javascript">
        (function($){
            $( 'form.checkout' ).on( 'change blur', 'input[name^="payment_method"]', function() {
                setTimeout(function(){
                    $(document.body).trigger('update_checkout');
                }, 250 );
            });
        })(jQuery);
    </script>
    <?php
}

add_action( 'woocommerce_checkout_update_order_review', 'refresh_shipping_methods' );
function refresh_shipping_methods( $post_data ){
    // HERE Define your targeted shipping method ID
    $payment_method = 'cod';
    $bool           = true;

    if ( WC()->session->get('chosen_payment_method') === $payment_method )
        $bool = false;

    // Mandatory to make it work with shipping methods
    foreach ( WC()->cart->get_shipping_packages() as $package_key => $package ){
        WC()->session->set( 'shipping_for_package_' . $package_key, $bool );
    }
    WC()->cart->calculate_shipping();
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

To be able to get the correct shipping method ID you can use your browser inspector, this way:

You may need to empty cart before testing this code.
