Instantiating Prefabs at run time

Question

I'm trying to move my project to Addressables and upload assets, prefabs and screens to an archive on the server.
I'm a new in Unity and this a bit challenging for me.
I've prepared all prefabs for addressable usage and now I'm trying load them.

All my prefabs have loads throw GameObject.Instantiate For example:

    public class PlatformObject : LocationObject
        {
//other properties and methods
            public PlatformObject Clone()
            {
                var clone = ((Runner.PlatformObject)GameObject.Instantiate(this));
                clone.Id = this.Id;
                clone.NextPlatforms = this.NextPlatforms;
                clone.IsStartPlatform = this.IsStartPlatform;
                clone.Level = this.Level;
                clone.Type = this.Type;
                clone.MinimumDistance = this.MinimumDistance;
                clone.AllowDispose = false;
                clone.Size = this.Size;
                return clone;
            }
    }

I've tried change this code for usage Addressables.

public async Task<PlatformObject> Clone()
        {
            var handle = Addressables.LoadAssetAsync<GameObject>(this.name);
            var clone = (await handle.Task).GetComponent<PlatformObject>();
            clone.Id = this.Id;
            clone.NextPlatforms = this.NextPlatforms;
            clone.IsStartPlatform = this.IsStartPlatform;
            clone.Level = this.Level;
            clone.Type = this.Type;
            clone.MinimumDistance = this.MinimumDistance;
            clone.AllowDispose = false;
            clone.Size = this.Size;
            return clone;
        }

I've got a cloned object successfully, but object doesn't appears on the scene. Looks like object not initialized properly, bcouz I've got a lot of warnings like that:

Setting the parent of a transform which resides in a Prefab Asset is disabled to prevent data corruption (GameObject: 'Mid_Town_07'). UnityEngine.Transform:set_parent(Transform)

I've googled and have found a few solution related with parent location. Made changed but it didn't help. I'm still getting those warnings.

You will need to also Instantiate the object before setting it's parent transform as it's not yet an instance when you call LoadAssetAsync.

See the docs here: https://docs.unity3d.com/Packages/[email protected]/manual/AddressableAssetsGettingStarted.html

Notably this line:

Addressables.InstantiateAsync("AssetAddress");

Or alternatively once you have the GameObject, instantiate it as normal.
