I have a very annoying problem on my Magento 2.3.3 installation. The composer doesn’t work properly. I can’t run any composer update, composer require etc. Every-time I try to do that, it gives me this error:
Fatal error: Uncaught TypeError: Return value of MagentoInventoryComposerInstallerPlugin::initModuleDeployment() must be an instance of MagentoInventoryComposerInstallervoid, none returned in /vendor/magento/inventory-composer-installer/src/Plugin.php:69
Stack trace:

Before answer this question saying “This is a compatibility issue, try to verify your memory limit, php version etc etc”, this is NOT a compatibility issue.
I have enough memory limit and I have PHP 7.1 installed.
PS, even if I try to run the composer ignoring requirements (--ignore-platform-reqs) it gives me the same error!
PLEASE, I need somebody to help me on that!
