Unreal Engine 5.1打包项目启动触发EXCEPTION_STACK_OVERFLOW崩溃求助

基于Widget制作了一个简单的点击器项目，保存并打包归档后启动项目时出现崩溃，报错为EXCEPTION_STACK_OVERFLOW，相关堆栈信息如下：

Unhandled Exception: EXCEPTION_STACK_OVERFLOW

从堆栈信息看，FLinkerLoad的导入验证环节出现循环调用，导致栈溢出，这类问题通常和Widget或资源的循环引用有关，按以下步骤排查：

• 检查自定义Widget类的引用关系：确认是否存在A Widget引用B Widget、B又引用A的情况，重点看蓝图变量、父类设置或子Widget嵌套逻辑。
• 清理项目损坏资源：打开项目后执行编辑器右上角文件->验证内容修复损坏引用；删除项目根目录下的DerivedDataCache文件夹，清理缓存后重新打包。
• 检查打包设置：确认未勾选强制包含未使用资源的选项；尝试用开发打包模式替代Shipping模式，获取更详细的报错信息。
• 简化项目测试：暂时移除点击器项目中自定义的Widget逻辑，只保留最基础的Widget结构，打包测试是否崩溃，逐步添加功能定位问题点。
• 检查蓝图循环依赖：打开所有相关蓝图，查看变量、事件图表里是否有互相调用的逻辑，比如WidgetA构造函数创建WidgetB，WidgetB构造函数又创建WidgetA。
