Drupal 9 + Fivestar = ajax 500

In version 9 of Drupal, when editing the display of the fivestar rating field, the following error may appear - when you click on the field options gear (to change the rating style or edit the displayed value), nothing happens, and an error is written in the console

Drupal\Core\Security\UntrustedCallbackException: Render #pre_render callbacks must be methods of a class that implements \Drupal\Core\Security\TrustedCallbackInterface or be an anonymous function. The callback was Drupal\fivestar\Plugin\Field\FieldFormatter\StarsFormatter::previewsExpand. See https://www.drupal.org/node/2966725 in Drupal\Core\Render\Renderer->doTrustedCallback() (line 96 of /sites/site.com.ua/web/core/lib/Drupal/Core/Security/DoTrustedCallbackTrait.php).

To fix this error, apply the following patch
