Python 我的tkinter代码因按钮或输入框而崩溃

最近我想开始学习tkinter，但我的代码有问题。当我运行它，我可以登录，但在我登录后，它崩溃。我不知道为什么会发生这种情况，并尝试了一些事情。 我已经设法使文本出现（重新排列），所以我确信它是按钮或输入框

你能比“it崩溃”更具体一点吗？它是如何崩溃的？你有错误吗？如果是这样的话，错误是什么？当我运行代码并完成登录过程时，我按下登录按钮，然后它会按应有的方式清除所有内容，但是tkinter画布没有响应，因此我必须关闭它。它可能会变得无响应，因为您有一个无限循环。是否添加了调试语句以查看代码正在执行的操作？一旦你进入循环，

gay

就不可能变成

False

。我可能会在周一（下次可以）检查这种情况，谢谢你的帮助
