Runtime Exception

In updating to the 8.x-2.0 version of the module, I'm getting PHP errors, which result in WSOD situations, on some builds.

Interestingly enough, I can replicate it regularly in some PHP 7.2.x environments, but not others.

This is with the same DB, and same codebase. The logged error I get is:

RuntimeException: The native PHP intl extension (http://php.net/manual/en/book.intl.php) is needed to use intl-based filters. in Twig_Extensions_Extension_Intl->__construct() (line 17 of /vendor/twig/extensions/lib/Twig/Extensions/Extension/Intl.php).

In the site status report, I see a notice about the Twig Extensions Intl not being active, for both environments.

In addition, I'm pretty sure I'm not calling this extension in any code.
