When attempting to set the .result of an async, if async.executing is True, the call to .executing = True will raise an exception. That exception is caught in the final except clause, which attempts to set the result to an exception, which raises another exception because the Task isn't executing.
The solution would probably involve explicitly catching the NotExecutingError and doing something other than attempt to write it to the Async.result.

NotExecutingError
NotExecutingError: The Async must be executing to set its result.
