Core NFC reports stack error in the modal intermittently. What is this error?

Howdy,

I seem to have a reliability issue when reading a type 5 tag where I get this "Stack Error", but only sometimes. Other times, the reads are completing without an issue. The delegate's readerSession(:didInvalidateWithError:) is reporting type 200 (user cancelled) even though that doesn't seem to be the case. It looks like Core NFC is cancelling the session itself...

What does this mean?

Thanks, smkuehnhold

Did you ever find the reason to this, or/and a potential solution?
