I ran the following commands:

git clone git clone [email protected]:brianzinn/create-react-app-typescript-babylonjs.git
cd create-react-app-typescript-babylonjs
pnpm install
npm start

I got the following output & error:

i think just need to update typescript and ts-node. i've been getting errors on many different projects lately. thanks for reporting - I need to update this project React version and make sure some other reported issues are fixed downstream as well! 😄
