Invalid request (Unexpected EOF) - Orange 5.4

Question

I’m having a problem using Laravel 5.4, suddenly the site stopped working (locally) and gives this error in the server (cmd) and the site does not load. In the browser console error 500 appears when loading localhost.

No CMD aparece Invalid request (Unexpected EOF) conforme abaixo:
$ php artisan serve
Laravel development server started: <http://127.0.0.1:8000>

In the Apache and PHP log, memory error appears, but I have already increased to 2048 and the error continues. I tested the same site on my laptop, and there works normal.

PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 130968 bytes) in D:\wamp64\www\Vandaflex2018\vendor\laravel\framework\src\Illuminate\Container\Container.php on line 748
