Custom task start method throws an ArgumentException

Question

Due to the fact that CultureInfo is not copied from stream to stream, I made the following method to do this for me.

public static StartCustomTask(Action action, TaskCreationOptions tco = TaskCreationOptions.None)
{
    var currentCult = Thread.CurrentThread.CurrentCuture;
    var currentUiCult = Thread.CurrentThread.CurrentUICulture;

    return Task.Factory.StartNew(() =>
    {
        Thread.CurrentThread.CurrentCuture = currentCult;
        Thread.CurrentThread.CurrentUICulture = currentUiCult;
        action();
    }, tco);
}

basically this code copies culture information from the current thread to the thread that it should execute action. I don’t know why, but he quits System.ArgumentExceptionspeaking Value does not fall within the expected range. I tried to run the action on the main thread regularly and it works fine. By this, I mean that this method, which is an action, has no problem, a problem arises somewhere in the above code.

Here is the exception stack trace

one more thing. this code worked fine, but suddenly he started to do it.
