Resize image with intervention/image

I have a function to save the picture, and I need it to reduce the picture with the specified size. I decided to use the package intervention/image. I installed the package with composer require intervention/image. Then I made changes to my function. In the end it turned out like this:

Controller:

use Intervention\Image\Facades\Image;
if ($request->hasFile('preview_image')) {
    $file = $request->file('preview_image');
    $namewithextension = $file->getClientOriginalName();
    $name = explode('.', $namewithextension)[0];
    $extension = $file->getClientOriginalExtension();
    $uploadname = $name. '-' .DateTime::createFromFormat('U.u', microtime(TRUE))->format('U-u') . '.' .$extension;
    $img = Image::make($file)->resize(240, 120);
    $article_block_image->preview_image = $img->save(public_path('public/article-block-image/preview' , $uploadname));
}

Model:

public function getOriginPreviewImageUrl() {
   return $this->attributes['preview_image'];
}

public function getPreviewImageAttribute($value) {
    return Storage::exists($value) ? Storage::url($value) : null;
}

When I try to upload a picture I get this error.

"message": "Can't write image data to path (D:\wamp64\www\test\public\public/article-block-image/preview)", "exception": "Intervention\Image\Exception\NotWritableException", "file": "D:\wamp64\www\test\vendor\intervention\image\src\Intervention\Image\Image.php",`

$path = public_path('public/article-block-image/preview' . $uploadname);

Image::make($image->getRealPath())->resize(468, 249)->save($path);

Run command: php artisan storage:link
