How to force a client-side Crash?

I have a really odd question.. Normally, it should be the other way around, you'll tell me..


But wait, hear me out : Is there a way to Force a player to crash as if he did ALT-F4 ?

To keep it short: I have a secret mob, that may be summoned through only few specific conditions, and i'd like them to make the player "Crash" once touched.
It is planned to be played on a server, so it would be nice if not the whole world broke or everyone got DC'd.

A short example of what i want would be : Secret Mob Seen -> Chase -> If touches player -> Crash their game (Possibly jumpscare too before because might aswell be a jerk to the fullest.).
