Storage::exists returns false

Hi, i'm writing a section in my product controller that checks if the old product image exist and then delete it before updating with the new image path

        $newImageName = $product->id.'-'.$request->image->getClientOriginalName();
        $newImage = $request->image->move(public_path("images/product/$product->id"),$newImageName);
        $oldPath = public_path("images/product/$product->id/").$product->image;

        if (Storage::exists(public_path("images/product/$product->id/").$product->image)){
            dd('File is exists.');
        } else {
            dd('File not exist');
        }

$oldPath value ="C:\laragon\www\mini\public\images/product/11/11-20119342_10_400.jpg" and it confirm exists. but it always returns fail.

i have no issue uploading the new file in the which will be in "C:\laragon\www\mini\public\images/product/11\11-20112633_01_400.jpg"

is it because of the \ and / since i'm using windows?
