Warning after update SEOPress plugin from 7.4 to 7.5.1

Greetings,
after updating the SEOPress plugin from 7.4 to 7.5.1 a Warning notice appears on the articles of the website https://www.formasalus.it/.

Warning: preg_match_all(): Unknown modifier ‘0’ in /home/formasal/public_html/wp-content/plugins/wp-seopress/src/Services/ContentAnalysis/GetContent.php on line 22

SEOPress: 7.5.1

SEOPress Pro: 7.5

I have currently rolled back to version 7.4 where this error is not present. Any help would be appreciated.
