Updating a nested field outside the loop causes white screen within a repeatable field.

update_sub_field( array( 'cpt_ids', 1, 'cpt_id' ), $cptID );

I know this is a pretty old topic and you’ve probably moved on by now, but for others that are looking for help with white screen of death issues the fist step is to enable debugging in WP so that you can see information about why php is dying.

// in wp-config.php
define('WP_DEBUG', true );
define('WP_DEBUG_DISPLAY', true);
