Why can't it find the route in Laravel?

Question

Laravel

For some reason, the user.account route does not work, it gives an error:

Route [user.account] not defined. (View: /Users/vladimir/Desktop/lbog/resources/views/layouts/app.blade.php)

. After changing the routes, I wrote the php artisan route:clear command. The error is shown because of the sidebar in the template.

<ul class="navbar-nav ml-auto">
                @guest
                    <li class="nav-item">
                        <a class="nav-link" href="{{ route('auth.login') }}">Login</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="{{ route('auth.register') }}">Sing up</a>
                    </li>
                @else
                    <li class="nav-item">
                        <h4>{{ Auth::user()->name }}</h4>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="{{ route('user.account') }}">My account</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="{{ route('auth.logout') }}">Logout</a>
                    </li>
                @endif
            </ul>

Route::group([
    'as' => 'user',
    'prefix' => 'user',
    'namespace' => 'User',
    'middleware' => ['auth'],
], function(){
    Route::post('account', [App\Http\Controllers\User\AccountController::class, 'account'])->name('account');
});

class AccountController extends Controller
{
    public function account(Request $request){
        return view('user.account');
    }
}
