Fatal error: Uncaught exception what to do?

Question

PHP

Good afternoon, I'm just starting to learn all the delights of programming. And going through the next video lesson, I wanted to repeat the example that is indicated in it, but I got a Fatal error at the output and I just can’t understand what the reason is. Please help me because I can't continue learning until the code

works Fatal error: Uncaught exception 'core\base\exceptions\RouteException' with message 'Error' in D:\OSpanel\OSPanel\domains\Test.com\index.php: 43 Stack trace: #0 D:\OSpanel\OSPanel\domains\Test.com\index.php(36): C->__construct() #1 D:\OSpanel\OSPanel\domains\Test.com\index.php (29): B->__construct() #2 D:\OSpanel\OSPanel\domains\Test.com\index.php(19): A->__construct() #3 {main} thrown in D:\OSpanel\ OSPanel\domains\Test.com\index.php on line 43

Here is the code itself

use core\base\exceptions\RouteException;

try {
    (new A());
}
catch (RangeException $e) {
    exit($e->getMessage());
}

class A
{
    public function __construct()
    {
        (new B());
    }
}
class B
{
    public function __construct()
    {
        (new C());
    }
}
class C
{
    public function __construct()
    {
        throw new RouteException('Ошибка');
    }
}

You need to catch the same error (RouteException) or a common one (Exception)
