I add this Code On bootstrap/app.php

$app->bootstrapWith([
\Illuminate\Foundation\Bootstrap\LoadEnvironmentVariables::class,
\Illuminate\Foundation\Bootstrap\LoadConfiguration::class,
\Illuminate\Foundation\Bootstrap\HandleExceptions::class,
\Illuminate\Foundation\Bootstrap\RegisterFacades::class,
\Illuminate\Foundation\Bootstrap\SetRequestForConsole::class,
\Illuminate\Foundation\Bootstrap\RegisterProviders::class,
\Illuminate\Foundation\Bootstrap\BootProviders::class,
]);

new Error after added this code :

And run composer dumpautoload -o, it doesn't work

I added this code , it works

$app->bootstrapWith([
\Illuminate\Foundation\Bootstrap\LoadEnvironmentVariables::class,
\Illuminate\Foundation\Bootstrap\LoadConfiguration::class,
\Illuminate\Foundation\Bootstrap\HandleExceptions::class,
\Illuminate\Foundation\Bootstrap\RegisterFacades::class,
\Illuminate\Foundation\Bootstrap\SetRequestForConsole::class,
\Illuminate\Foundation\Bootstrap\RegisterProviders::class,
\Illuminate\Foundation\Bootstrap\BootProviders::class,
]);

but i use sluggable package and set method to config file , after set command , change sluggable package method array to this :

'method' =>
  Closure::__set_state(array(
)),

Now , my app doesn't work! Because comment this code and work my code ! :(
