Debugging new Device Type - ST has crashed but a report has been sent to the developer

I’m trying to debug my EZMultiPli Device Type which was working and I was able to see the device on by tablet and interact and debug it.
But now when I click on the Gear in the upper right corner of the device to see the details, ST crashes and says it has sent a report to the developer.
I get the same thing on my Nexus 10 and my android phone - the ST app just crashes.
But I don’t get anything so I assume the “developer” is someone within ST?

So now I’m stuck until it starts working again.
I’ll try putting the old code back in but I haven’t changed anything that significant so I’m not sure why it’s not working.

Maybe @duncan can give me a clue?

Sounds like something in your metadata is triggering a bug in the app. The mobile devs do look at those crash reports, and it might be something that has been fixed in the upcoming release. Can you post the metadata?
