Upload Control Causes Application to Quit

I’ve been having an issue with an application that just quits unexpectedly when I upload a file, and I just found that I can replicate the issue with the WiseJ Demo Browser. Here’s how to replicate it:

1. Download the Demo Browser from here:https://github.com/iceteagroup/wisej-demobrowser
2. Run it and navigate to the Editors -> Upload section.
3. Select the Choose Image button, choose an image.

At this point, the application shows the “Offline” message and just quits. This is the same thing that is happening in my application.

Update: This is related to the Upload control. Using it in 3.5.11 crashes my app and the demo app.

Please see the screenshot attached, and if so desired, download the Demo Browser and see for yourself.

Any ideas on how to fix this? I’ve been looking into it for about a week now and I’m glad to be able to replicate it with the Demo Browser… hopefully someone knows what’s going on here?

FYI here is what shows up in the browser console:
