When I write code like I change DB::commit(); what makes the code go down i want it to be quiet and not move because it is very annoying

i trying for restart extension but this not work

 //

        dd($request->all());
        $validated = $request->validate([
            'name' => ['required', 'string', 'max:255'],
            'cover' => ['required', 'image', 'mimes:png,jpg,jpeg'],
            'path_file' => ['required', 'file', 'mimes:zip'],
            'about' => ['required', 'string', 'max:65535'],
            'category_id' => ['required', 'integer'],
            'price' => ['required', 'integer', 'min:0'],
        ]);

        DB::commit();
