Unity构建后IntroModalScreenPanel无法激活，编辑器运行正常

问题概述 #

• 已尝试论坛所有推荐解决方案，耗时5天仍未解决
• 问题仅出现在Windows/Mac/Linux平台的构建包中，Unity编辑器内运行完全正常
• 【2022年12月1日补充】首次使用“Build and Run”构建并运行时无问题，但关闭后通过.exe文件重启游戏，问题依然存在

问题详情 #

场景中的IntroductionHUD为Canvas，TestText（TextMeshPro）用于检测IntroModalScreenPanel（Image）的激活状态，IntroModalScreenManager（空物体）挂载脚本负责控制IntroModalScreenPanel及其子物体的激活与失活。

IntroModalScreenManager的Awake方法会将IntroModalScreenPanel及其子物体设置为失活状态，脚本中通过SetActive(bool)方法控制物体状态，所有物体均已在Inspector中赋值。

但构建包中，IntroModalScreenPanel在Awake失活后无法再次激活，TestText检测显示该面板始终处于未激活状态。同一Canvas下的Background和TestText运行正常，仅IntroModalScreenPanel及其子物体受影响。
