I have this error that makes me impossible to continue using SSH. I am installing MAGENTO 2.3.2 extensions

Fatal error: Class Magento\Setup\Mvc\Bootstrap\InitParamListener contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Zend\ServiceManager\Factory\FactoryInterface::__invoke) in /home/vaporartuk/public_html/setup/src/Magento/Setup/Mvc/Bootstrap/InitParamListener.php on line 33

Does someone know how to correct it?
