PHP Fatal error: Declaration of Robo\Common\ConfigAwareTrait::getConfig() must be compatible with Drush\Commands\DrushCommands::getConfig(): Drush\Config\DrushConfig in /var/www/html/vendor/consolidation/robo/src/Common/ConfigAwareTrait.php on line 34

Describe the bug

On a new Drupal 11 project, doing drush si produces this error:

PHP Fatal error: Declaration of Robo\Common\ConfigAwareTrait::getConfig() must be compatible with Drush\Commands\DrushCommands::getConfig(): Drush\Config\DrushConfig in /var/www/html/vendor/consolidation/robo/src/Common/ConfigAwareTrait.php on line 34

To Reproduce

Installed Drupal on PHP 8.3, with the version of Drush that Composer installs by default.

Workaround

None other than hacking the file vendor/drush/drush/src/Config/ConfigAwareTrait.php by hand to remove the return type from getConfig().

System Configuration

Q	A
Drush version?	13.6.0
Drupal version?	11.1.7
PHP version	8.3.19
OS?	Mac, using ddev

Additional information Add any other context about the problem here.

Seems like you have an odd version of consolidation/robo in your vendor. Maybe try to update that.

[joachim-n]

Should Drush then declare a minimum version of consolidation/robo to prevent this?

[weitzman]

AFAIK, we do already. If we dont its a bug.

[joachim-n]

Well this was a clean D11 install, and Composer installed that version of robo.

Also, I've just cloned 5.x of robo, and it has in Robo\Common\ConfigAwareTrait:

    public function getConfig()
