System Timer main thread

I am using a Timer (System.Timers.Timer) to countdown to an action which should call a static method from another class. My code is the following:

 timer = new System.Timers.Timer();
 timer.Interval = 1000;
 timer.Elapsed += this.OnTimedEvent ;
 timer.Enabled = true;
 
 private void OnTimedEvent(object source, System.Timers.ElapsedEventArgs e)
     {
         ApplicationModel.SaveLifeNumber (1);
     }

In ApplicationModel my code is:

 public static void SaveLifeNumber(int life)
 {
     currrentLives = currrentLives + life;
 
     PlayerPrefs.SetString("currentLives", currrentLives.ToString());
 }

My error is:

TrySetSetString 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.

I know that System.Timers.Timer calls the OnTimedEvent on a non-UI thread but i was not able to find a way to do it on the main thread.

I tried using
