middleware conflicts with controller __construct middleware (request validation error not working)

Question

I am using middleware for user roles. But when I am using middleware in Controller __construct method, request validation does not work properly. It doesnt show any errors, session error bag returns null. I am not able to see any errors when form submit. But when I have disabled middleware in construct I can see request validation errors.

web.php middleware + controller _construct middleware = request validation doesnt works.

web.php middleware + without _construct middleware = works fine.

without web.php middleware + _construct middleware = works fine.

I showed the details in my codes.

I tried every method for a week but I couldn't solve it. I look forward to your help sincerely.

web.php

Route::group(['middleware' => ['client.role:paying']], function () {
    Route::get('/pay_section', 'HomepageController@showPaySection');
    Route::get('/pay_success', 'HomepageController@showPaySuccess');
    Route::get('/pay_error', 'HomepageController@showPayError');
    Route::post('/pay_section', 'HomepageController@doPaySection');
});

HomepageController (like this my form request validation doesnt works because of middleware)

public function __construct()
{
$this->middleware(function ($request, $next) {

    $client = auth()->guard('client');
    if ($client->check()){
        $request->session()->put('client_id', $client->user()->id);
    }else{
        $request->session()->put('client_id', -1);
    }

    $this->_cid = $request->session()->get('client_id'); // client
    View::share(['cid' => $this->_cid]);
    return $next($request);
});
}

HomepageController (like this my codes works perfect. I am able to see request validation errors there is no problem.)

public function __construct()
{

   $this->_cid = 2; // client
   View::share(['cid' => $this->_cid]);
}

Middleware ClientRole.php

public function handle($request, Closure $next, ...$roles)
{


    $currentRole = array();
    $client = auth()->guard('client');


    if ($client->check()){
        $currentRole[] = 'client';
    }else{
        $currentRole[] = 'guest';
    }

    if (session()->has('shop_cart')) {
        $currentRole[] = 'shopping';
    }

    if (session()->has('order')) {
        $currentRole[] = 'paying';
    }

    $currentRole[] = 'paying';
    foreach($roles as $role) {
        if(in_array($role, $currentRole))
            return $next($request);
    }

    return redirect('/');

}

HomepageController form action

public function doPaySection(CreditcardRequest $request)
{

    $validated = $request->validated();

    // it doesnt show any errors when form empty. But it should be.
    // without middleware it shows error on my view when form empty. 

}

View

     <div class="messages">
            @if ($errors->any())

You may set SESSION_DRIVER=file in you .env file

Then run php artisan config:clear
