提交任何表格后Laravel期满

Question

当我在laravel中提交表单时，用户会话过期，并且注销了当前用户。我以为是csrf令牌问题，所以我禁用了它的验证功能，但问题仍然存在。

我的观点

 <form action="{{url('/save-user-details')}}" method="POST" enctype="multipart/form-data" 
                >
                    @csrf    
                        <div class="row">
                            <div class="col-md-6">
                                <div class="form-group">
                                    <label>Primeiro Name</label>
                                    <input type="text" class="form-control"
                                    name="firstName" required>
                                </div>
                            </div>
                            <div class="col-md-6">
                                <div class="form-group">
                                    <label>Apelido</label>
                                    <input type="text" class="form-control" name="lastName" required>
                                </div>
                            </div>
                        </div>


                        <button type="submit" class="button pull-right" value="">Actualizar Perfil</button>    
                    </form>

我的路线列表

Route::post('/save-user-details', 'DashboardController@saveUser');
Route::get('/editar-usuario', 'DashboardController@editProfile');

我的控制器

public function __construct()
{
    $this->middleware('auth');
}
public function saveUser(Request $request){
    $user_id = auth()->user()->id;
    $user = User::find($user_id);

        $detalhes = new Detalhesuser;
        $detalhes->user_id = $user_id;
        $detalhes->firstName = $request->input('firstName');
        $detalhes->lastName = $request->input('lastName');
        $detalhes->profissao = $request->input('profissao');
        $detalhes->instituicao = $request->input('instituicao');
        $detalhes->biografia = $request->input('biografia');
        $detalhes->save();
        $user->detalhesUser_id = $detalhes->id;
        $user->save();


    return redirect('/dashboard')->with('success', 'Detalhes salvos');
}

我的会话存储在文件中。我试图将其更改为数据库，问题仍然存在。

知道我在哪里做错了吗？
