I've tried substituting "cred_submit_complete" for "wp_insert_post" but it keeps throwing a critical error.

/**
  * Description: Sets the invoice number the first time an auction vehicle is saved based on what the previous highest invoice number and incrementing by "1".
 */

// only create invoice number if the post in new, NOT an update
function set_invoice_number( $post_id, $post, $update ) {
	if ( wp_is_post_revision( $post_id ) ) {
        return;
	}

	if ( 'auction-vehicle' == $post->post_type ) {
		if( !$update ){
            $args = array(  
                'post_type' => 'auction-vehicle',
            );
            $myloop = new WP_Query( $args );
            
            //loop through all posts of this post type to find the highest invoice number
            $find_highest_id = 0;
            while ( $myloop->have_posts() ) : $myloop->the_post();
                $this_post_id = get_the_ID();
                $invoice_number = get_post_meta( $this_post_id, 'wpcf-invoice-number', true );
                if($invoice_number > $find_highest_id){
                    $find_highest_id = $invoice_number;
                }
            endwhile;
            wp_reset_postdata();
            
            //take the highest value and increment it then save as client id for the new client
            $invoice_number = $find_highest_id + 1;
            update_post_meta( $post_id, 'wpcf-invoice-number', $invoice_number);
        }
	}
}
add_action( 'wp_insert_post', 'set_invoice_number', 10, 3 );

Hello,

When you get the "critical error" message, that means there are some PHP error in your website, please follow our document to get the PHP debug logs:
https://toolset.com/documentation/programmer-reference/debugging-sites-built-with-toolset/#php-debugging

Then fix your custom PHP codes.

I took a different approach.
