Hi @christian_meyer
You can try this.
In vendor/magento/module-translation/Model/Json/PreProcessor.php
$area = $this->areaList->getArea($areaCode);
$area->load(\Magento\Framework\App\Area::PART_TRANSLATE);
needs to be:
$area = $this->areaList->getArea($areaCode);
$area->load(\Magento\Framework\App\Area::PART_DESIGN);
$area->load(\Magento\Framework\App\Area::PART_TRANSLATE);
After making the changes run the below the commands from your magento root directory.
php bin/magento static-content:deploy -f
php/bin magento cache:flush
Hope it helps you!
Thanks
