Resolution Note:
The real problem is that for 'tvOS' there is a symbol defined as '69' and that is not valid. To fix this, simply go to Player Settings/tvOS and remove the offending symbol. The updater relies on a version of a library (Roslyn) that throws an exception instead of reporting an error. The newer versions of this library fixed this (and correctly reports an error instead of throwing an exception).
