Error: No class named WapplerSystems\WsLess\Hooks\RenderPreProcessorHook #31
Description
In TYPO3 v11.5.25 / ws_less 11.0.0 / php 8.1 when installing from TER I'm getting the following error:
Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1294585866: No class named WapplerSystems\WsLess\Hooks\RenderPreProcessorHook | InvalidArgumentException thrown in file /typo3_src-11.5.25/typo3/sysext/core/Classes/Utility/GeneralUtility.php in line 3131.
This occurs in an Upgraded installation from TYPO3 10, the error bricks the front- and backend making it unable to even have the extension installed for now.
