使用pywinauto读取文本时触发ElementNotFoundError问题求助

尝试读取UI文本时触发ElementNotFoundError，使用pywinauto recorder识别对象时，鼠标悬停在仅剩余字符'e'的模糊文本上时，工具会指向绿色空白区域。目前不清楚如何在pywinauto中处理这类问题，请求帮助。

注意：print_control_identifiers()方法可正常打印出目标文本对应的控件信息。

代码 #

app = Application(backend='uia').start(
    r"cmd.exe /c start AppName",
    create_new_console=True,
    wait_for_idle=False)
app = Application(backend='uia').connect(title_re="AppName", found_index=0, timeout=10).AppName  
print(app.print_control_identifiers())
print(app.child_window(title="foo boo e", control_type="Text",
                                              found_index=0).wrapper_object().window_text())

预期输出 #

All control identifiers hierarchy.
foo boo e

实际输出 #

Static - 'foo boo e'    (L603, T234, R728, B249)
    ['foo boo eStatic', 'foo boo e', 'Static54']
    child_window(title="foo boo e", control_type="Text")
