You need to change the PHP version from 7.1.27 to either 7.1.3 or 7.2.0. You can see more details on https://devdocs.magento.com/guides/v2.3/install-gde/system-requirements-tech.html.

Hope this will fix your issue

It looks like you are missing the mcrypt php extension.
I've read in various places that it's not that straight forward to install mcrypt on php 7.2.
But you can follow this tutorial on how to do it: https://www.techrepublic.com/article/how-to-install-mcrypt-for-php-7-2/
