It’s been fixed, it only generates the unique ID once now.

function yl_create_unique_id_acf_field( $value, $post_id, $field ) {

	// Check if the field already has a value
	if ( !empty( $value ) ) {
		return $value; // If it already has a value, return it.
	}

	// If no value, generate a new unique ID
	$uniqueid_length = 9;
	$uniqueid = crypt(uniqid(rand(), 1));
	$uniqueid = strip_tags(stripslashes($uniqueid));
	$uniqueid = str_replace(".", "", $uniqueid);
	$uniqueid = strrev(str_replace("/", "", $uniqueid));
	$uniqueid = substr($uniqueid, 0, $uniqueid_length);
	$uniqueid = strtoupper($uniqueid);

	$title = 'WRE-' . $uniqueid;

	// Save the generated ID to the ACF field
	update_field( 'account_id', $title, $post_id );

	return $title;
}
add_filter('acf/load_value/name=account_id', 'yl_create_unique_id_acf_field', 10, 3);
