After all these months, I finally figured it out!

Changed in version 3.8: CancelledError is now a subclass of BaseException rather than Exception.

The sampling process got cancelled, but it didn't get removed from the sample cache. So now you're basically always awaiting a cancelled future, which throws a CancelledError that isn't caught by any of my normal except clauses because they're written as except Exception as err:, which, for the attentive listeners out there, is not a base class of CancelledError.
