When I install your Extension in the latest github version at an TYPO3 10.4.21 (classic installation, php 7.2.23) and open a page with the plugin I got the following error when entering the frontend:

(1/2) #1278450972 TYPO3\CMS\Extbase\Reflection\Exception\UnknownClassException

Class Webschmiede\SessionPopup\Controller\PopupController does not exist. Reflection failed.

(2/2) #-1 ReflectionException

Class Webschmiede\SessionPopup\Controller\PopupController does not exist

In my case I changed
ext_localconf.php
8: in 'KKSoftware.SessionPopup',

and in
Classes/Controller/PopupController.php
2: in namespace KKSoftware\SessionPopup\Controller;

I will check it :)
The extension is not even used by us in production but nevertheless thanks for reporting.

I will prepare a PR

There's also a mention of webschmiede in ext_tables.php
