Thank you for reply. If i correct understand, i write this code in funtions.php

add_action( 'wp_ajax_my_acf_update2', function(){
  // Get post id
  $post_id = $_POST['post_id'];
  // Get id another post from the relation field
  $another_post_id = get_field('Blocks-FirstSlide-copyBlock', $post_id );
  // Getting data
    $source_fields = get_field_objects($another_post_id);
    //Creating response
    $response = array();
    foreach ($source_fields as $field) {
  $response[$field['key']] = $field['value'];
    }
    echo json_encode($response);
    exit;
    });

and this code in script:

jQuery( function ( $ ) {
  $ ('.acf-field-64647e4980e03').click( function(){
    var input = $(this);
    var post_id = $('#post_ID').val();
    $.ajax({
      type : 'POST',
      url : ajaxurl,
      data:{
        action:'my_acf_update2',
        post_id: post_id
      },
      success: function(data) {
        for (var key in json) {
  var field = acf.getField(key);
  field.val(json[key]);
}
      }
    });
  } ); 
} );

Result:
Uncaught ReferenceError: json is not defined
at Object.success
