Wordfence Fatal Error

Hello everyone,

I have problems with GP Premium and Wordfence on some websites. The Wordfence scans show the following error and then stop:
Fatal error: Uncaught Error: Attempt to assign property "plugin" on bool in /wp-content/plugins/gp-premium/library/class-plugin-updater.php:342 Stack trace: #0

WordPress 6.1.1
Generate Press 3.2.4
GP Premium 2.2.2
Wordfence 7.9.1
php 8.0

I tried the tips from https://www.wordfence.com/help/scan/troubleshooting, also uninstalled Wordfence completely with all tables and data and then reinstalled it.

What can I do? Thank you for help
