Magento 2 – Class not found

I always get this error if I try to load my site, even though the class does exist.

PHP Fatal error:  Uncaught Error: Class 'Company\App\Observer\Frontend\Controller\ActionPredispatch'

app/code/Company/App/etc/frontend/events.xml:

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="controller_action_predispatch">
        <observer name="company_app_observer_frontend_controller_actionpredispatch_controller_action_predispatch"
                  instance="CompanyAppObserverFrontendControllerActionPredispatch"/>
    </event>
</config>

app/code/Company/App/Observer/Frontend/Controller/ActionPredispatch.php:

<?php
declare(strict_types=1);

namespace CompanyAppObserverFrontendController;
    
class ActionPredispatch implements MagentoFrameworkEventObserverInterface
{
    ...
}

I tried this:

rm -rf generated/*
php bin/magento setup:di:compile

But I still get the error.
