Problem with user meta fields “The results cannot be loaded.”

This is the user’s meta field. It is added by another plugin to some users.
It’s a plugin I wrote myself. Below is a sample code that changes the value of the “folder_name” field

function ufm_save_folder_name_field($user_id)
{
  if (!current_user_can('edit_user', $user_id)) {
    return false;
  }

  if (current_user_can('administrator')) {
    $folder_name = isset($_POST['folder_name']) ? sanitize_text_field($_POST['folder_name']) : '';

    // If "Not Selected" is chosen, set $folder_name to an empty string
    if ($folder_name === 'Not Selected') {
      $folder_name = '';
    }

    update_user_meta($user_id, 'folder_name', $folder_name);
  }
}

Take a look at this explanation: https://help.dynamic.ooo/en/articles/4952541-dynamic-visibility-triggers-user-role

I tried to enter the field name from the example, but I still get an error.

Below is a list of current versions of some plugins, maybe it will be useful.

Dynamic Visibility for Elementor Version 5.0.11
Elementor Version 3.22.2
Elementor Pro Version 3.17.1

Thanks for your help!
