starting timer during prestart seems to sometimes cause an "ActorInitializationException: Exception during creation"

@brah-mcdude can you provide some actor code that we can look at in order to help reproduce?

[Aaronontheweb]

Just for clarification: this bug affects actors who use IWithTimers and call the StartTimer method inside the actor's PreStart override

[Aaronontheweb]

I tried to reproduce this @brah-mcdude

async Task Main()
{
	// Initialize Actor System
	var system = ActorSystem.Create("MySystem");

	// Create Props for the EchoActor
	var props = Props.Create<EchoActor>();

	// Create the EchoActor
	var echoActor = system.ActorOf(props, "echoActor");

	// Send 10 messages to the EchoActor
	for (int i = 0; i < 10; i++)
	{
		echoActor.Tell($"Message {i + 1}");
	}

	// Allow some time for messages to process before shutting down
	await system.WhenTerminated;
}

// Define the EchoActor class
public class EchoActor : ReceiveActor, IWithTimers
{
	private readonly ILoggingAdapter _log = Context.GetLogger();
	private int _msgCount = 0;
	public ITimerScheduler Timers { get; set; }

	public EchoActor()
	{
		NormalBehavior();
	}

	private void NormalBehavior()
	{
		ReceiveAny(message =>
		{
			_log.Info("Hit {0}", _msgCount++);
			if(_msgCount >= 10){
				Context.System.Terminate();
			}
		});
	}

	private class RecoverMarker { }

	protected override void PreRestart(Exception ex, object message)
	{
		Timers.StartPeriodicTimer("foo", "bar", TimeSpan.FromMilliseconds(100));
	}

}

Worked normally - what's the issue?
