PHP Fatal Error trying to install

Problem/Motivation

I get the following OGO Fatal error when I try to install the module:

PHP Fatal error:  Declaration of Drupal\convert_bundles\Routing\RouteSubscriber::getSubscribedEvents() 
must be compatible with Drupal\Core\Routing\RouteSubscriberBase::getSubscribedEvents(): array in 
/var/www/html/web/modules/contrib/convert_bundles/src/Routing/RouteSubscriber.php on line 79

Steps to reproduce

• Install module via composer
• Try to enable module using Drush
