First I call Addressables.ReleaseInstance(gameObject) function, then call Addressables.LoadAssetAsync(loadPath) function in the same frame. If gameObject and loadPath belong to the same bundle, it will casuse an error.

ArgumentException: An item with the same key has already been added. Key: Library/com.unity.addressables/StreamingAssetsCopy/aa/Android/Android/A.bundle

I’ll flag for the team to take a look! Which version of the Addressables package are you using?
