脚本在尝试渲染文本时每隔一次初始化它就会崩溃

Question

所以我正在尝试自学 Python，作为一个项目，我正在尝试使用 pygame 创建游戏 Connect 4。我已经实现了一个显示所有图块坐标的调试功能，但是当我激活它时（将变量“调试”设置为“1”，每隔一次我尝试初始化脚本时，它就会变成黑色并崩溃。其他 50% 的情况下，它工作正常。当我禁用文本渲染时它不会发生。但是，我不知道为什么会发生这种情况，并且在我的控制台中没有收到任何错误报告。

我正在使用 Pygame 2.0.1 在 Python 3.7 中通过 Anaconda3 发行版编写 Spyder。

这是代码。有问题的行似乎是 41-43 和 75-79，但我不知道可能出了什么问题。有谁知道可能是什么问题？不同的字体也会发生这种情况。

当它显示“来自 pygame 社区的您好”时。它可以工作，当它什么也不显示，或者只显示 'runfile()' 行时，它会崩溃。

我仍然不知道出了什么问题，但似乎不是代码。我将 Python 版本更新到 3.9.5，并通过另一个下载器而不是 Anaconda3 下载了我正在使用的 IDE 的新版本。这些事情中的任何一个都可能已经解决了它，但它不再崩溃了！
