The app displays some html content in an WebView. All I know about this crash is that it could be related to embedded videos widgets:

Is this bug related to React Native platform? Would an update of RN fix the issue?

This issue could be related to Javascript core crash when using YouTube iframe player in UIWebView in iOS 11.3 because of the React Native WebView...

The app content which is displayed in webview can be normal html text or instagram, facebook or youtube scripts/iframes ...
