I am trying to run a local cluster for the example hello wold program on GitHub but I keep running into these pop-up errors when I run the "solana-test-validator" command and I'm not sure why. For context, I am on a machine running Windows 11, running cmd prompt in administrative mode, and I have tried re-installing the Solana CLI tool but am still seeing these errors.

If we use the Hello World program provided by Solana Labs as reference, that program increments a counter every time a user interacts with the program:

The Solana helloworld example client is written in TypeScript. I found it hard to read because its extensive use of global state. To try and help future users and to learn a little about it myself I made an implementation of the example client in Rust which I find to be slightly more readable.

In this article, we'll walk through the process of sending a custom instruction to a solana on-chain program. We'll modify the solana example helloworld to take two instructions, SayHello and SayGoodbye.

Solana has a nice hello-world example that shows us how to build a Rust program on Solana from scratch and interact with it using a typescript SDK.
