Hi @moltar exactly which file needs to be changed?

[moltar]

I'm not sure, tbh. It's an old issue; the context got evicted from my brain. 😂

I have investigated it, npm run start doesn't work on windows, it throws an error,

Putting node here:

const cmd = ['node', ...process.argv.slice(0, 2), 'run-internal', c];

in index.ts

But as we support bun now and maybe deno in the feature this is not the correct fix
