Error with TestBlockDisplayVariant Class

[davidjguru]

Hi, I'm trying run drupal-check inside a Drupal project, but I'm unable to get the right feedback. This is giving me back a PHP Fatal error constantly.

PHP Fatal error: Cannot declare class Drupal\Tests\ctools\Unit\TestBlockDisplayVariant, because the name is already in use in /var/www/html/ctpdandalucia/web/modules/contrib/ctools/tests/src/Unit/BlockDisplayVariantTest.php on line 90
Launching drupal-check -ad web/modules/contrib/ return a message:
"PHPStan crashed in the previous run probably because of excessive memory consumption."
but I have the PHP memory limit set to -1 in cli and Apache...so what can I do?

My Drupal (output from drush status):
Drupal version : 8.6.14
PHP binary : /usr/bin/php7.2
PHP config : /etc/php/7.2/cli/php.ini

Greetings,
David.

I cannot reproduce. The autoloading has been improved, too. Can you try the latest drupal-check?
