Upgrade to Laravel 6 - Uncaught Error: Class 'Request' not found in app/Exceptions/Handler.php

I am currently upgrading from L5.8 to L6. I have read over the upgrade docs and made changes where necessary, if any. Once I changed the composer.json version to ^6.0 and ran composer update, I am getting the following stack trace.

This is on macOS running php 7.4

This is the Handler.php file its referencing to

<?php

        if ($exception instanceof HttpException === false) {
            $request = Request::all();
            Log::info("Error on page: " . Request::url());
            Log::info("Request data: " . htmlspecialchars(json_encode($request)));
        }

        parent::report($exception);
    }

    /**

     */
    public function render($request, Exception $exception)
    {
        return parent::render($request, $exception);
    }
}

line 43: $request = Request::all();

I have tried to run php artisan config:cache and php artisan config:clear but still get the following stack trace.

I am most likely focusing on the wrong part of the stack trace. Hopefully its not something obvious I am over looking.
