File upload not properly and update also but images working perfectly

Here is my STORE code

public function store(Request $request) {
        $request->validate([
            'bgImage' => 'required|image|max:2000|mimes:jpeg,bmp,png',
            'aboutMeImage' => 'required|image|max:2000|mimes:jpeg,bmp,png',
            'aboutMeHeading' => 'required|string',
            'aboutMeDignity' => 'required|string',
            'aboutMeDescription' => 'required|string',

            'aboutMeCV' => 'required|file|max:2000'
        ]);

        $aboutStore = new AboutUs();

    //Image uploading for about us background image
        //Find form bgImage and storing into a variable
        $bgImage = $request->file('bgImage');
        //Creating image upload time
        $currentDate = Carbon::now()->toDateString();

        //Using if statement and ensuring form data is available
        if (isset($bgImage)){
            //Creating image slug
            $slug = str_slug("about-us-bg-image");
            //Make unique name for image
            $bgImageName = $slug. '-'. $currentDate. '-'. uniqid(). '.'. $bgImage->getClientOriginalName();

            //Checking image storage folder, if not available then create a folder
            if (!Storage::disk('public')->exists('aboutUs')){
                Storage::disk('public')->makeDirectory('aboutUs');
            }

            //Save image and resize image
            $aboutUsBgImage = Image::make($bgImage)->resize(1920, 450)->stream();
            //And now put the image into storage disk
            Storage::disk('public')->put('aboutUs/'.$bgImageName,$aboutUsBgImage);

            //And save data into the database
            $aboutStore->bgImage = $bgImageName;
        }

        //Find form aboutMeImage and storing into a variable
        $aboutMeImage = $request->file('aboutMeImage');

        //Using if statement and ensuring form data is available
        if (isset($aboutMeImage)){
            //Creating image slug
            $slug = str_slug($request->aboutMeHeading);
            //Make unique name for image
            $aboutMeImageName = $slug. '-'. $currentDate. '-'. uniqid(). '.'. $aboutMeImage->getClientOriginalName();

            //Checking image storage folder, if not available then create a folder
            if (!Storage::disk('public')->exists('aboutUs')){
                Storage::disk('public')->makeDirectory('aboutUs');
            }

            //Save image and resize image
            $aboutUsImage = Image::make($aboutMeImage)->resize(600, 450)->stream();
            //And now put the image into storage disk
            Storage::disk('public')->put('aboutUs/'.$aboutMeImageName,$aboutUsImage);

            //And save data into the database
            $aboutStore->aboutMeImage = $aboutMeImageName;
        }

        $aboutStore->aboutMeHeading = $request->aboutMeHeading;
        $aboutStore->aboutMeDignity = $request->aboutMeDignity;
        $aboutStore->aboutMeDescription = $request->aboutMeDescription;

        //Find form aboutMeCV and storing into a variable
        $aboutMeCV = $request->file('aboutMeCV');

        //Using if statement and ensuring form data is available
        if (isset($aboutMeCV)){
            //Creating cv slug
            $slug = str_slug("about-me-cv");
            //Make unique name for cv
            $aboutMeCVName = $slug. '-'. $currentDate. '-'. uniqid(). '-'. $aboutMeCV->getClientOriginalName();

            //Checking cv storage folder, if not available then create a folder
            if (!Storage::disk('public')->exists('aboutUs')){
                Storage::disk('public')->makeDirectory('aboutUs');
            }

            //And now put the cv into storage disk
            Storage::disk('public')->put('aboutUs/'.$aboutMeCVName,$aboutMeCV);

            //And save data into the database
            $aboutStore->aboutMeCV = $aboutMeCVName;
        }

        $aboutStore->save();

        return redirect()->route('about.index')->with('success', 'About content saved successfully !');
    }

Here is my UPDATE code

$aboutUpdate = AboutUs::findOrFail($id);

    //Image uploading for about us background image
        //Find form bgImage and storing into a variable
        $bgImage = $request->file('bgImage');

        //Using if statement and ensuring form data is available
        if (isset($bgImage)){
            //Creating image slug
            $slug = str_slug("about-us-bg-image-updated");
            //Make unique name for image
            $bgImageName = $slug. '-'. $currentDate. '-'. uniqid(). '.'. $bgImage->getClientOriginalName();

            //Checking image storage folder, if not available then create a folder
            if (!Storage::disk('public')->exists('aboutUs')){
                Storage::disk('public')->makeDirectory('aboutUs');
            }

            //Delete old image from database
            if (Storage::disk('public')->exists('aboutUs/'. $aboutUpdate->bgImage)){

Thanks
