Python Tkinter 创建顶层时出错，消息框弹出 Tk_GetPixmap：CreateDIBSection 出错，操作成功完成

Question

我正在用 Python 3.10 中的 tkinter 创建一个二维码生成器，它可以生成可用于不同事物的二维码并将它们保存在本地文件系统中，它还可以调整二维码的大小。

代码未完成，但我遇到了顶层窗口的问题。错误是当我按下启动顶层的按钮时，带有 show .info 消息框类型的消息框显示此信息，标题：Tk_GetPixmap：来自 CreateDIBSection 的错误，消息：操作成功完成。当我按下确定时，两个 tkinter 窗口都会冻结大约 2 秒然后崩溃。

如果有人能帮我解决这个问题，那就太不可思议了。如何测试它或下载代码：转到我的 GitHub 存储库（链接）并按照 README.md 文件中的说明进行操作

记得下载包！

代码：
