我正在尝试为我的实用程序创建一个简单的工具包，以加快我在 Maya 中的工作流程。
第二次执行代码时，它总是崩溃，并且我无法找到错误的原因。
从我的角度来看，这是持有 Qt 小部件并造成崩溃的错误，但我无法解决它。

对于任何搜索类似错误的人，我发现在 qt connect 中使用 lambda 发送“变量”数据似乎会影响 Maya 并导致错误，经过部分测试但有相同的错误。
self.allToAces.pressed.connect(lambda: self.colorSpaceImages("all", "acesCg"))
self.allToRaw.pressed.connect(lambda: self.colorSpaceImages("all", "uRaw"))
self.selectedToAces.pressed.connect(lambda: self.colorSpaceImages("selected", "acesCg"))
self.selectedToRaw.pressed.connect(lambda: self.colorSpaceImages("selected", "uRaw"))
