crash on activation

I installed complianz and on activation my system had a fatal error which I could only get rid of by removing the pluginfolder by ftp. I am using the generatepress theme. The error message is:

WordPress-Version 5.8.3
Aktuelles Theme: GeneratePress Child (Version 0.1)
Aktuelles Plugin: Complianz | GDPR/CCPA Cookie Consent (Version 6.0.5)
PHP-Version 8.1.0
