Here is the solution:

Edit inside this file path:

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

Replace With:

$this->area = $this->emailConfig->getTemplateArea($templateId);
}
return $this;
