"Intervention Image" upload image file Corrupted.

I'm using "Intervention Image" to uploading an image in my Laravel project. Image upload successfully but the image file corrupted. Now how I fix this problem.

Create.blade.php

<form action="{{ route('admin.category.store') }}" method="POST" enctype="multipart/form-data">
                            @csrf
                            <div class="form-group form-float">
                                <div class="form-line">
                                    <input type="text" id="name" class="form-control" name="name">
                                    <label class="form-label">Category Name</label>
                                </div>
                            </div>
                            <div class="form-group">
                                <input type="file" accept="image/*" name="image">
                            </div>
                            <button type="submit" class="btn btn-primary m-t-15 waves-effect">Submit</button>
                            <a href="{{ route('admin.category.index') }}" type="button" class="btn btn-danger m-l-5 m-t-15 waves-effect">Back</a>
                        </form>

Category Controller

public function store(Request $request)
    {
        $this ->validate($request,[
           'name' => 'required|unique:categories',
           'image' => 'required|mimes:jpg,jpeg,png,bmp',
        ]);
        //Get Image From Form
        $image = $request->file('image');
        $slug = str_slug($request->name);
        if (isset($image))
        {
            //make unique name for image
            $currentdate = Carbon::now()->toDateString();
            $imagename = $slug.'-'.$currentdate.'-'.uniqid().'.'.$image->getClientOriginalExtension();

            //Check Category folder if exist
            if (!Storage::disk('public')->exists('category'))
            {
                Storage::disk('public')->makeDirectory('category');
            }
            //resize image for category & Upload
            $category = Image::make($image)->resize(1600,479);
            Storage::disk('public')->put('category/'.$imagename,$category);

            //Check Category Slider folder if exist
            if (!Storage::disk('public')->exists('category/slider'))
            {
                Storage::disk('public')->makeDirectory('category/slider');
            }

            //resize image for category slider & Upload
            $slider = Image::make($image)->resize(500,333);
            Storage::disk('public')->put('category/slider/'.$imagename,$slider);
        }
        else
        {
            $imagename = "default.png";
        }
        $category = new Category();
        $category->name = $request->name;
        $category->slug = $slug;
        $category->image = $imagename;
        $category->save();
        Toastr::success('Category Successfully Save','Success');
        return redirect()->route('admin.category.index');
    }
