            } catch (ResponsableInterface|DeprecatedRedirectException $e) {
                $this->outputBufferingEnd();
                if ($e instanceof DeprecatedRedirectException) {

            } catch (Throwable $e) {
                $this->outputBufferingEnd();

                throw $e;
            }
        }$this->response = $this->handleRequest($routes, config(Cache::class), $returnResponse);
            } catch (ResponsableInterface|DeprecatedRedirectException $e) {
                $this->outputBufferingEnd();
                if ($e instanceof DeprecatedRedirectException) {
                    $e = new RedirectException($e->getMessage(), $e->getCode(), $e);
                }

                $this->response = $e->getResponse();
            } catch (PageNotFoundException $e) {
