invokerepeating meathod didn't allow other script to run in unity 3D

Question

Two Script is attached with my one scene in unity , in one script i used method invokerepeating when it is called , my second script which is attached with the buttons didn't work.

void Start()
{
    currentImage = 0;
    if (thread == null) {
        thread = new Thread (new ThreadStart (CallChangeImage));
        thread.IsBackground = true;
        thread.Start ();
    }
}

public void CallChangeImage()
{
    InvokeRepeating("ChangeImage", 0.1f, frameRate);
}

private void ChangeImage()
{
    if (currentImage == frames.Length - 1)
    {
        CancelInvoke("ChangeImage");
        Destroy(explosion);
    }
    currentImage += 1;
    explosion.sprite = frames[currentImage];
}

when i used this invokerepeating in other thread, it gave error this method only invoke in main thread. After calling this scene, i didn't go back to any other scene because my all code is going to be stuck. Help me solve this problem!!

Unity's API is not thread safe, which means in order to use methods inside unity's api you must go through the main thread, for what purpose are you using that thread? — Ido Ben Shalom, Oct 29 '17 at 11:03

this is the correct way to do it without the use of threads

void Start()
{
    currentImage = 0;
    InvokeRepeating("ChangeImage", 0.1f, frameRate);
}

private void ChangeImage()
{

        if (currentImage == frames.Length - 1)
        {
            CancelInvoke("ChangeImage");
            Destroy(explosion);
        }
        currentImage += 1;
        explosion.sprite = frames[currentImage];

}
