cannot add new device

Unfortunately, not really. It does confirm it was in XCWorkerThread, which is what I suspected.

It looks like it's successfully processed a pile of channels before that, but eventually encountered a channel that it doesn't like. Probably missing something it expects, like a name or similar

I can see that it does indeed process a pile of channels before encountering the error.  Unfortunately now I'm stuck.

That absolutely did the trick and allowed me to import successfully.  Hats off to you!
