Using classes from MagentoSetup namespace in custom module

This is for Magento 2.4.13-p3, on PHP 7.4.

I’m working on a custom console command class. It uses another custom class named Analyzer in its constructor. I’m trying to inject a MagentoSetupModelInstallerFactory dependency into the Analyzer class constructor, and it doesn’t work:

<?php

namespace UtpcExplainerModel;

use MagentoSetupModelInstallerFactory;

class Analyzer {

    protected InstallerFactory $installerFactory;

    public function __construct(
        InstallerFactory $installerFactory
    ) {
        $this->installerFactory = $installerFactory;
    }

    // etc....

With that constructor, when you run bin/magento it throws this:

Fatal error: Uncaught Error: Cannot instantiate interface LaminasServiceManagerServiceLocatorInterface in /var/www/html/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php:50
Stack trace:

It seems to do this if you try adding any class in MagentoSetup... as a dependency. It also happens if I try creating the InstallerFactory class using object manager directly instead of adding it as a dependency. Anyone know why?
