OSSError: WinError 6 句柄无效

[kingname]

Everything is ok when I use macOS to run the code. But when I use windows 10, the exception alway raised when I call an element's 'exists' property.

My Python is Python 3.6, both in macOS and WIndows 10.

The related code is:

search_icon_bar = self.device(text='Show', instance=0)
        if search_icon_bar.exists:`

Traceback (most recent call last):

my python3.6 also meets this issue, any way to resolve this ?
