Resolved Resources.UnloadUnusedAssets does not free memory.

I am using Unity 2021.3.2.

After creating the game object with Resources.Instantiate, the memory was released on UnityEditor by destroying the game object and executing Resources.

UnloadUnusedAssets, but when the build is executed later on the browser (Chrome), the memory is not released. It was.

Can you tell me how to free the memory?

 

I noticed the cause of this problem.

The Manual states that in many cases freeing obsolete memory does not reduce the size of the managed heap.

It also stated that it would not be reduced but would be reused.
When I checked the contents, I was able to confirm that the memory was being reused.

It is this page that I referred to.
