Help React app loads and disappears

My renderer helper is working just fine. When i Console log what is being rendered i get the full app with content working and then a second console log but content is gone in the app and then thats when page goes blank. So when view the app the page is viewable for like .5secsonds and then disappears.

in your renderer.js … if I remove this line it loads:

<script src="client_bundle.js"></script>

If I take this out javaScript won’t work and button won’t console.log anything when clicked.
