Help solving Uncaught Abort on HTML5 Build [closed]

For some reason there is a Invoke that is triggered when a button is clicked that causes my game to crash. Any idea how I can sort this out?

I have plenty other Invokes and none has given problems. I have the Enable Exceptions option set to None and game works fine inside Unity.

I can give more info on the error if you can point to me to what's relevant. Thanks so much!

EDIT: Here is the code generating the error:

    public void OnClick()
    {
        if (buyCoal.interactable == true) 
        {            
                trainObject.trainMovementStart();

                if (SceneManager.GetActiveScene().name == "Level1" || SceneManager.GetActiveScene().name == "Level2")
                    Invoke("coal_refill", 6f);

                if (SceneManager.GetActiveScene().name == "Level3")
                    Invoke("coal_refill", 12f);

                Money.UseMoney(coalcost);
                buyCoalAudio.Play();
                countdown += 1; //agora é count up
                tipCoalReady = 2;
                buyCoalButtonIndex = 0; //DISABLE COAL Buy Button
                coal_stock_countdown.text = countdown.ToString();
                coaltipCounter += 1;                    
        }
    }

    void coal_refill()
    {
        ThermoElectric.quota += 17.5m;
        Invoke("reactivateBuyCoalButton", 5f);
    }
    void reactivateBuyCoalButton()
    {
        buyCoalButtonIndex = 1;
    }
}

}
