Whatever the reason I would like to figure out a way to catch this and stop the reactor either in process, or by another process monitor.  Any suggestions either twisted or otherwise would be greatly appreciated.

Presumably the QtWebEngineView is running a subprocess, then?  This is really a Qt question rather than a Twisted question, because the QtWebEngineView should be emitting some kind of signal when its rendering process crashes.  (If it doesn't I imagine you're just out of luck here and you should report a bug to the Qt developers...)
