Fatal error using 'Star rating'

Hi everyone, After the last Windows update I have a serious problem with an application that uses Star Rating.(PHPRUNNER 10.91)
When I open the page that uses it I get this error:
"Fatal error: Uncaught Error: Class 'ViewStarRating' not found in D:\xampp7413\htdocs\rp_verifiche_2.0_v11_nostar\include\phpfunctions.php...etcetera"
I found this post: https://asprunner.com/forums/topic/27769-fatal-error/page and tried all the proposed solutions, without solutions
I also tried to edit the fields that use star ratings in the project, but phprunner often closes during editing.
Is there a way to remove references to Star Rating from the project ? Or anything else?
Thanks for your suggestion
Mauro
