OSError: [Errno 22] Invalid argument

Additional context Maybe, it's worth handling not just ValueError but OSError as well in the 'create' method?

@dataclasses.dataclass
class OutputReceivedEvent:
    pid: int
    date: int
    message: str

    @classmethod
    def create(cls, message) -> 'OutputReceivedEvent':
        try:
            date = datetime.datetime.fromtimestamp(message[2].value)
        except ValueError: 
            date = None

        return cls(pid=message[1].value, date=date, message=message[0].value)

Printing the 'message' that causes the error gives the following output:

ListContainer: 
Container: 
    type = 2
    value = u'AK Info: Number of detected and '... (truncated, total 62)
Container:
    type = 3
    value = 79293
Container:
    type = 6
    value = 106543509355060

Thanks for the very detailed issue report! I tried testing it with com.apple.mobilesafari on my mac but wasn't able to reproduce it - making me suspect this is a windows-specific issue.

Could you test adding the OSError handling resolves the issue and submit a PR?

Yeah, sure, thanks
