Sometimes things get marked as spam for various reasons.

My understanding is that you have an options page with a repeater on it and you want to populated a select field with the values of that repeater.

because select field is a sub field in a flex field you should use the field key for your filter.

add_filter('acf/prepare_field/key=FIELD KY OF SELECT', 'populate_FIELD_NAME_from_options');
function populate_FIELD_NAME_from_options($field) {
  $choices = array();
  if (have_rows('repeater_name', 'options') {
    while (have_rows('repeater_name', 'options') {
      the_row();
      $choices[get_sub_field('value_sub_field')] = $get_sub_field('label_sub_field');
    }
  }
  $field['choices'] = $choices;
  return $field;
}
