将cocos2d-x移植到HarmonyOS上之后运行的过程中经常发生高概率崩溃的问题，崩溃栈如下，看起来是崩溃在WorkerThreads上的，请问通过WorkerThreads线程来运行cocos2d-x是否有隐患？

1）关于cocos2d-x在WorkerThreads线程上运行是否有隐患，需要检查下是否试图在WorkerThreads线程上直接操作UI控件。

2）注意到崩溃日志中多次出现了：

AddCleanupHook Failed.

是否使用了napi_add_env_cleanup_hook函数？

NODE_EXTERN napi_status napi_add_env_cleanup_hook(node_api_nogc_env env,napi_cleanup_hook fun,void* arg);

解决方案

一旦当前Node.js环境退出，将fun注册为要使用arg参数运行的函数。可以使用不同的arg值安全地多次指定一个函数。

在这种情况下，它也会被多次调用。不允许多次提供相同的fun和arg值，否则会导致进程中止。

该函数的使用方法参考：https://nodejs.cn/api/n-api.html#napi_add_env_cleanup_hook
