The crash occurs intermittently on iOS devices.

[Sunny-guangge]

We’ve encountered an intermittent crash on iOS devices.
Below is the stack trace:

spine::Skeleton::updateWorldTransform() + 20
cocos2d::middleware::MiddlewareManager::update(float) + 136
cocos2d::middleware::MiddlewareManager::update(float) + 136
cocos2d::renderer::RenderFlow::render(cocos2d::renderer::NodeProxy*, float, cocos2d::renderer::Camera*) + 80

Could you please help check this?

There os absolutely no way any developer could figure out what's wrong from this stack trace. All entries except the last one are not in Spine code. I don't know which Cocos2d variant this is, nor which Spine Runtimes version is used (Cocos2d likes to pack their own version).

Unless you can provide a reproduction project with which I can reproduce and devug this, I afraid there's nothing I can do.
