the code quality tool on git.drupalcode.org had this to say about the line:

Description
Call to deprecated method renderPlain() of interface Drupal\Core\Render\RendererInterface: in drupal:10.3.0 and is removed from drupal:12.0.0. Use \Drupal\Core\Render\RendererInterface::renderInIsolation() instead.
