Error calling the method ViewsRenderPipelineMarkup::getUntranslatedString() n the SharethisWidgetBlock.php file

Problem/Motivation

Getting the error:

The website encountered an unexpected error. Please try again later.
Error: Call to undefined method Drupal\views\Render\ViewsRenderPipelineMarkup::getUntranslatedString() in Drupal\sharethis\Plugin\Block\SharethisWidgetBlock->build() (line 194 of modules/contrib/sharethis/src/Plugin/Block/SharethisWidgetBlock.php).

Steps to reproduce

Install the latest version of Sharethis module and run it in a Drupal 9.2 environment.

Temporal resolution

I haven't been able to properly fix the issue. Thus I have just removed the troublesome code with the attached patch as my website does not use the title field.
THE PATCH DOES NOT FIX THE ISSUE!
