Unity3D sub-thread cannot modify the main thread object state

Scenario where the problem occurs

Unity Socket programming, after communicating, the Unity side received a string of JSON characters from the server, and then modified a GameObject property in GameManager.cs based on the JSON value, and then an error was reported. What I modified was a Text text box. the text inside. The error is as follows, which probably means that things in the main game thread cannot be modified in the sub-thread. This is easy to understand, because the Socket communication itself will have a communication process. This is not the main process of Unity but an independent process of C#. process, so something went wrong.

The error message is as follows:

Internal_CloneSingle can only be called from the main thread.
Constructors and field initializers will be executed from the loading thread when loading a scene.
Don't use this function in the constructor or field initializers, instead move initialization code to the Awake or Start function.
UnityEngine.Debug:Log (object)
SocketManagerController:Received () (at Assets/Scripts/SocketManagerController.cs:121)
System.Threading.ThreadHelper:ThreadStart ()

solution

I don't know how it is normally solved this way, because I am not professional in Unity, but I found that the Socket process can modify basic types, such as: string, int, bool.
So my approach is to do it in the Socket thread
