Fixed mistake with using $this in a static function

hello am having this issue

public static function createFromGlobals(): static
{
$request = self::createRequestFromFactory($_GET, $_POST, [], $_COOKIE, $_FILES, $_SERVER);

if (str_starts_with($request->headers->get('CONTENT_TYPE', ''), 'application/x-www-form-urlencoded')
&& \in_array(strtoupper($request->server->get('REQUEST_METHOD', 'GET')), ['PUT', 'DELETE', 'PATCH'])
) {
parse_str($request->getContent(), $data);
$request->request = new InputBag($data);
}

return $request;
