Question

这段代码基本上可以完成所需的工作。但是有时它确实会引发错误，而我希望代码能够正常工作，因为所有必要的数据都存在。

它的作用是：（1）读入用户（2）将信息添加到Excel仪表板，例如标题信息，词云和个人资料图片。

然后保存Excel文件。有时，几乎随机地会产生错误：（pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, 'Microsoft Excel', 'Open method of Workbooks class failed', 'xlmain11.chm', 0, -2146827284), None)）。代码的哪一部分可能导致这种情况？

发生异常（..）-'Microsoft Excel'，'SaveAs ...类失败'
