App stops after SMS API Call

I am having an interesting issue when sending an SMS message. I am currently using the C# SDK and testing through the sandbox.

I'm not sure if it's because of the size of the message or what. If I just have the "Hello from C#", it sends the message, but if I try to add my own message, it will call the SMS endpoint and then my program stops. Not in an error stop way, but it shuts off the debugger.

For the message, I have kept it under 160 characters, including the "watermark" text you all add to the front while sending in sandbox. I have the call in a try/catch and it's odd that if the call is erroring out, it would have been caught in the catch block.

Code Example:

 var parameters = new CreateSMSMessage
                {
                    from = new MessageStoreCallerInfoRequest { phoneNumber = fromNumber },
                    to = new MessageStoreCallerInfoRequest[] { new MessageStoreCallerInfoRequest { phoneNumber = phone} },
                    text = $"To see your results use access key - Access Key: {accessKey} - https://bit.ly/whatever"
                };
try
{
    //This is the call that after it executes, it will stop Visual Studio debugging
    //It shows as a success in analytics, but doesn't send a message
    var resp = await ringCentral.Restapi().Account().Extension().Sms().Post(parameters);
    var msgStatus = resp.messageStatus;
}
catch(Exception ex)
{
   //Handling the exception
}

UPDATE: It is also doing it when I use the "Hello from C#" as the text parameter. It's probably not a text message size issue, but nothing is throwing an error.
