Python 3.x 出现异常（..）-“Microsoft Excel”、“另存为…”。。。类失败'

这段代码基本上完成了它需要做的事情。但它有时确实会抛出错误，而我希望代码能够在所有必要数据都存在的情况下工作

因此，它所做的是：1读入用户2向Excel仪表板添加信息，例如标题信息、词云和配置文件图片

然后保存Excel文件。它有时几乎是随机地给出一个错误：pywintypes.com_error:-2147352567，“发生异常”，0，“Microsoft Excel”，“工作簿类的打开方法失败”，“xlmain11.chm”，0，-2146827284，无。代码的哪一部分会导致这种情况
