Reproduction

// build.mjs
import { build } from 'esbuild-wasm';

build({
    entryPoints: ['main.ts'],
    bundle: true,
}).then(console.log)

// main.ts
export default 42

Additional information

When using Yarn PnP, the error message is different. Not sure if it is the same error or not

git bisect points to https://github.com/nodejs/node/commit/00b2f07f9ddeb8ffd2fb2108b0ed9ffa81ea000d (https://github.com/nodejs/node/pull/54160) which has a revert PR open at https://github.com/nodejs/node/pull/55527.

I didn't look into why the process doesn't terminate though.
