Symfony error Undefined variable: _COOKIE in initial bootstrap.php.cache. What to do?

Question

symfony

We have php 7.1.5 , Symfony 2.7 (originally developed under php 5.3)
The project worked for a week and then crashed.

Notice: Undefined variable: _COOKIE in D:\dev\ntb\app\bootstrap.php.cache on line 493
Fatal error: Uncaught TypeError: Argument 4 passed to Symfony\Component\HttpFoundation\Request::createRequestFromFactory() must be of the type array, null given,

There is no access to apache. What are the considerations? How is it possible on this line

$request = self::createRequestFromFactory($_GET, $_POST, array(), $_COOKIE, $_FILES, $server);

Other projects on this server are working.
I guess that perhaps the server was rebooted and the cache broke. If it's the cache. How to turn it off completely?
Really need help!
