Electron Helper crashes when refreshing while devtools is paused

Description

I'm currently working on a nodes project that seems to crash Electron Helper when I hit cmd+R while devtools is paused at a debugger statement.

Steps to Reproduce

The project calls require(' ts-node/require') then require('index.ts') to start my app, which might be relevant to reproduce. The debugger statement resides in the index.ts (which is transpired and loaded with inlined source maps by ts-node.

1. Launch iron-node within the project folder: iron-node ./index.js
2. Wait for devtools to pause at a debugger statement.
3. Hit cmd+R

Expected behavior:

Reloads without issues.

Actual behavior:

Reloads but shows Problem Report for Electron Helper

Reproduces how often:

The crash seems to occur consistently on every reload even after relaunching iron-node and restarting, upgrading iron-node and dependencies, but in rare occasion while testing it sometimes stopped happening without clear cause.

It never happened when I manually pause devtools, as opposed to dynamically pausing by calling debugger, before hitting cmd+R.

At some point when I tried to replicate this by calling debugger from index.js, I could no longer reproduce it, even when I stepped through to the debugger statement in index.ts. I even removed the debugger statement from index.js to revert to the initial scenario and it no longer crashed when dynamically paused from index.ts. I simply don't have a clue what could have changed.

This has been happening for a few months, with different versions of every aspect involved (Iron-node, electron, node, typescript, ts-node, macOS, you name it), and it is not restricted to this one project, but most of my projects will usually require ts-node/require so it remains a potential factor but not necessarily the cause.

Sorry: I tried to do some leg work, but I can't seem to figure iron-node's internals enough to debug the issue. But I am available to help you with any troubleshooting or testing you need.
