Works for me on generate:form:config, which suffered the same problem.

Please provide some information why this PR was closed.

This PR solved my problem with config:export:single I had in both Console 1.8.0 and 1.9.0.

@fonata was closed because we were unable to preoduce in latest version 1.9.0, please test again and if fails, please let us now how to reproduce to reopen.

@enzolutions Here is a slightly artificial command that allows to reproduce the problem:
drupal config:export:single --name=system.site --remove-config-hash --remove-uuid --module=webform --optional

It crashes for Console 1.9.0, but not with this PR. I am using Drupal Core 8.7.2 and PHP 7.1.29.

Despite the scary error message, the YAML file seems to be created correctly.

Here is the output for Console 1.9.0:

christian@lenovo-pc /var/www/hub/vendor/drupal/console ((1.9.0)) $ drupal config:export:single --name=system.site --remove-config-hash --remove-uuid --module=webform --optional
