In this particular case, the Script path field is set wrong:

• Script path in the task should be set to ” /var/www/vhosts/example.com/httpdocs/bin/magento"
• with arguments field should be filled as "cron:run"
• "/usr/bin/php" should not be presented in Script path field due to the fact that PHP is defined by Use PHP version field
