Hello Metaplex Dev team/ OS gang;

Anyone came across this issue ? I literally just followed the getting started and got hit with this on the first line of code. Would appreciate any takes on how to solve this!

    "@metaplex-foundation/mpl-token-metadata": "^3.2.1",
    "@metaplex-foundation/umi": "^0.9.1",
    "@metaplex-foundation/umi-bundle-defaults": "^0.9.1",

const umi = createUmi('https://api.devnet.solana.com').use(mplTokenMetadata());
Uncaught runtime errors:

I tested with create-next-app from scratch and works fine. But fails with create-react-app v18&17
