Python 问题是什么？：application.connect（）错误

我是一个初学者，开始使用pywinauto学习自动化

使用application.connect（）连接到已打开的程序时发生溢出错误

但是application.start（）工作正常

如果有人知道这部分，请帮助我

源代码和错误内容如下所示

源代码：

import pywinauto

app = pywinauto.application.Application()

app.connect(title_re='Calculator')

如果您遇到问题，请尝试此方法。您必须说backennd是uia，它对我来说工作正常。

这应该是他桌面上的另一个应用程序的问题。它可以在pywinauto端处理，但我无法在自己端复制它。此问题可在此处跟踪：
