I am getting the above error as well, it seems to be when the renderBlock function is triggered and there is no resource available in the array to be built and therefore returns false every time.
This is for both Twig and PHP versions.

I downloaded https://github.com/bschussek/standalone-forms then I downloaded the dependences with composer and everything was fine.
But I'm getting the same error:
Fatal error: Uncaught exception 'Symfony\Component\Form\Exception\FormException' with message 'Unable to render the form as none of the following blocks exist: "_form_widget", "form_widget".' in ...dev\standalone-forms\vendor\symfony\form\Symfony\Component\Form\FormRenderer.php:221
