You're evaluating the (/ 1 0) before you make your evaluator. You have
to quote it.
The following works for me:
(define my-eval
(parameterize ([sandbox-output #f]
[sandbox-error-output #f]
[sandbox-propagate-exceptions #f]
[sandbox-propagate-breaks #f])
(make-evaluator 'racket)))
(my-eval '(/ 1 0))
