Drush shows fatal error when running on a Drupal root

I just installed a new copy of Drupal 7 with CiviCRM and everything works without problems, as well as Drush (installed locally), but not when I run it in the Drupal root directory, the following tantrum is immediately deleted:

drupuser @ ip-172-00-00-00: / var / www / drupal7 $ drush

I tried to debug it by editing module.inc and, after running drush again on the root, I dropped the extremely large query.
I tried the phar and composer installations, but both show the same message.
I have Drupal 7.61 and Drush 8.1.17 php 7.2
