No activating possible – Fatal error: Uncaught Error (PHP 8, current WP)

This plugin was downloaded but at activating I get following error message:

WP Version: 5.9.1
PHP Version: 8.1.1

Plugin could not be activated because it triggered a fatal error.

Fatal error: Uncaught Error: Call to undefined function error_log() in /home/users/USER/www/DOMAIN.TLD/wp-includes/wp-db.php:1582 Stack trace: #0 /home/users/USER/www/DOMAIN.TLD/wp-includes/wp-db.php(2103): wpdb->print_error() #1 /home/users/USER/www/DOMAIN.TLD/wp-includes/wp-db.php(2715): wpdb->query() #2 /home/users/USER/www/DOMAIN.TLD/wp-content/plugins/content-egg/application/models/Model.php(153): wpdb->get_var() #3 /home/users/USER/www/DOMAIN.TLD/wp-content/plugins/content-egg/application/models/AutoblogModel.php(555): ContentEgg\application\models\Model->count() #4 /home/users/USER/www/DOMAIN.TLD/wp-content/plugins/content-egg/application/Installer.php(55): ContentEgg\application\models\AutoblogModel::isActiveAutoblogs() #5 /home/users/USER/www/DOMAIN.TLD/wp-includes/class-wp-hook.php(307): ContentEgg\application\Installer::activate() #6 /home/users/USER/www/DOMAIN.TLD/wp-includes/class-wp-hook.php(331): WP_Hook->apply_filters() #7 /home/users/USER/www/DOMAIN.TLD/wp-includes/plugin.php(474): WP_Hook->do_action() #8 /home/users/USER/www/DOMAIN.TLD/wp-admin/plugins.php(194): do_action() #9 {main} thrown in /home/users/USER/www/DOMAIN.TLD/wp-includes/wp-db.php on line 1582
