Can you set all of them to use 5.1.0 and run npm install again?

You’re mixing [UMD and ES6 packages](https://dev.to/iggredible/what-the-heck-are-cjs-amd-umd-and-esm-ikm), which won’t work 🙂 You’ll either need to use the ES6 (prefixed with @babylon) or UMD (not prefixed) version, not both at the same time 🙂
