Android Studio：libgdx scene2d的InputMultiplexer在Release模式崩溃

• 现有一套已投入使用的游戏框架（多款应用基于该框架开发），在Gradle 7.4.2版本下，Debug和Release两种构建变体均能正常运行；升级至Gradle 8.1.1后，仅Debug版本可用，Release版本点击屏幕（真机或模拟器）会立即崩溃。
• 若注释掉BaseScreen的show()方法中与InputMultiplexer相关的代码，Release版本即可恢复正常运行。
• 另外发现：将构建变体从Debug切换至Release时，会弹出一个对话框，多次点击顶部的“选择模块”后错误提示消失，不确定这是否是问题的根源。
