This is a known issue in magento 2.2.4. It can be fixed by modifying the function setForcedArea() in Magento\Email\Model\AbstractTemplate.php

Update

public function setForcedArea($templateId)
 {     if ($this->area) {
         throw new \LogicException(__('Area is already set'));
     }
     $this->area = $this->emailConfig->getTemplateArea($templateId);
     return $this;
 }

To

public function setForcedArea($templateId)
 {     if (!isset($this->area)) {
         $this->area = $this->emailConfig->getTemplateArea($templateId);
     }
     return $this;
 }
