Unreal 4.27 升级 UDeveloperSettings unresolved external symbol

Question

我正在尝试将 Unreal 4.25.3 项目转换为 Unreal 4.27。我已经升级了我所有的插件（他们都说他们现在支持 4.27）并解决了一系列编译器错误，但我似乎无法在我的 classes.

我有一个名为 UStoreModeSettings 的 class，我在其中创建了一些新的项目设置配置变量。编译错误信息：

我仔细阅读了 4.27 Upgrade Notes，没有发现任何似乎会影响此内容的内容。

我绝不是 C++ 或 Unreal 专家，所以我希望至少有人能为我指出正确的研究方向。

谢谢！
