从cocos3.11.1升级上来的项目，以前在各平台都表现正常，升级为3.15后，
Windows 和 iOS正常，Android下执行如下代码：
std::string mainfestPath = “src/config/project.manifest”;
std::string storagePath = FileUtils::getInstance()->getWritablePath() + “target”;
_am = AssetsManagerEx::create(mainfestPath, storagePath);
_am->retain();
就会崩溃，去掉的话一切正常，@minggo 老师周末在吗？
