close

Closes an AssetBundle and releases the resources occupied by it.

This function overrides the close method to ensure that, even if the AssetBundle is destroyed, it does not affect resources that are currently in use. However, the AssetBundle itself becomes unavailable and the strong reference to any loaded resource is released. This is crucial for preventing memory leaks and ensuring that resources no longer needed are properly disposed of, while still allowing currently used resources to remain functional.

Closing an AssetBundle does not affect resources currently in use, but makes the AssetBundle itself unavailable and releases strong references to its loaded resources. This helps prevent memory leaks and ensures unused resources are properly disposed while allowing active resources to remain functional.
