In your create method, you dont need to to call validation service, try to use $this->validator->getErrors(), in your case may be like that:
return redirect()->to('/Create')->withInput()->with('errors', $this->validator->getErrors());
Or may be like this:
return redirect()->back()->withInput()->with('errors', $this->validator->getErrors());
And you dont need to check validation in your view anymore, just check if you has errors in session:
<?php if (session()->has('errors')) : ?>
<ul class="alert alert-danger">
<?php foreach (session('errors') as $error) : ?>
<li><?= $error ?></li>
<?php endforeach ?>
</ul>
<?php endif ?>
