The post is updated to Processing through native woocommerce usage ( inside the Order, it is switched to status “processing” and then pressed the button “Update”.

The field is a standard text field, available in the Order page to be edited, this is correct.

By the way when running the code with some form of debugging like this

add_action( 'woocommerce_order_status_processing', 'update_product_custom_field_', 10, 1 );
function update_product_custom_field_( $order_id ) {
    // Log start of function
    error_log("Updating custom field for order ID: $order_id");

    // Generate the shipping number using the order ID
    $shipping_number = 'SHIPPINGNUMBERHERE';

    // Check if ACF function exists and update the custom field
    if (function_exists('update_field')) {
        $result = update_field( 'order_shipping_number', $shipping_number, $order_id );
        if ($result) {
            error_log("Successfully updated order_shipping_number for order ID: $order_id");
        } else {
            error_log("Failed to update order_shipping_number for order ID: $order_id");
        }
    } else {
        error_log("ACF update_field function not found.");
    }
}

it prints to the logs “Successfully updated order_shipping_number for order ID:”

which makes it seem like the update_field is running correctly, but for some reason is not saving?
