I have reproduced this issue with few modifications and it worked for me

I have referred ms docs and used the below modified code which gave me result.

Code

using Azure.AI.OpenAI;
using Azure;

var key = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

string endpoint = "Your endpoint";
var client = new OpenAIClient(new Uri(endpoint), new AzureKeyCredential(key));

string deploymentName = "Your deployment name";
string prompt = "What is Azure OpenAI?";
Console.WriteLine($"Input: {prompt}");

Response<Completions> completionsResponse = await client.GetCompletionsAsync(deploymentName, prompt);
string completion = completionsResponse.Value.Choices[0].Text;
Console.WriteLine($"Chatbot: {completion}"); 

Output
