larvel 8 remove Providers/RouteServiceProvider.php namespace. Maybe you add back again.

 protected $namespace = 'App\Http\Controllers';  
...  
  
        $this->routes(function () {  
            Route::prefix('api')  
                ->middleware('api')  
                ->namespace($this->namespace)  
                ->group(base_path('routes/api.php'));  
  
            Route::middleware('web')  
                ->namespace($this->namespace)  
                ->group(base_path('routes/web.php'));  
        });

Add backup namespace then get problem for livewire. Every route just use App\Http|controllers ooxxooxxooxx.

OLD Way

  
web.php  
  
Route::resource('users', 'UsersController');  
Route::delete('users/destroy', 'UsersController@massDestroy');  
  
Get Error  
Route::resource('orders', 'livewire.order');  
Route::resource('orders', 'livewire@order');  
Route::view('orders', [\App\Http\Livewire\Order::class, 'render']);

Maybe Way

web.php  
  
Route::view('orders', 'livewire.order');  
  
Files:  
\app\Http\Livewire\Order.php inside use return view('livewire.order');  
\resources\views\livewire\order.blade.php   
  
Get Error  
Undefined variable: orders  or other ooxxooxx   
Alwasy get this Error. 
````````` ```
  
web.php  
  
Route::get('/admin/orders', [\App\Http\Livewire\Order::class, 'render']);  
  
Files:  
\app\Http\Livewire\Order.php    
And use  
return <<<'blade'  
blade;  
  
Get plain text @foreach($orders as o$key -> $permission   
Same Error.  

`````Beacuse view run first. Only create view then @livewire('')

example:  
order and orderlist

order view for fist(main) load page. orderlist be loaded by order view. order view have @livewire('orderlist').

or just remove namespace
------------------------

Route::get('/admin/orders', \App\Http\Livewire\Order::class);


Don't add namespace in app/Http/livewire/ any file. Always get errors.
