.Net: Bug: GroupChat does not produce result in Orchestration Package for 1.58 (.NET)

[arafattehsin]

Describe the bug
I have got an agent that uses the latest GroupChat within Microsoft.SemanticKernel.Agents.Orchestraiton package. Ever since I have updated it to 1.58.0-preview, it has stopped giving me an output.

string text = await result.GetValueAsync(TimeSpan.FromSeconds(ResultTimeoutInSeconds * 3)); the value of text is returned as empty string.

It can also be reproduced within the GettingStartedWithAgents tests.

It exists in 1.59 as well.

Same. Seems to work in 1.57.0. I did spend hours trying to figure out if I did something wrong here as I was building something new and not updating....

And with 1.59.0 there are other problems too. My GroupChatOrchestration fails after a number of invocations (3). But with 1.57.0 everything works. Getting an "exit code 134" whatever that means.

Confirmed the result isn't be surfaced as expected...digging into this now.
