Error: [remix] dest already exists - intermittent build error

Today my build started failing intermittently with the following error:

Error: [remix] dest already exists.
    at /vercel/path0/node_modules/fs-extra/lib/move/move.js:51:31
    at /vercel/path0/node_modules/universalify/index.js:21:38 {
  code: 'PLUGIN_ERROR',
  plugin: 'remix',
  hook: 'writeBundle'
}

There seems to be no pattern to it, sometimes a preview would build correctly and then the deploy to production would fail, sometimes the preview would fail. Retrying the same deploy multiple times does eventually seem to fix it.

I can’t exactly say how to reproduce as It’s not a consistent error.

I’m running Remix the Vercel Remix package, supabase and Vite. The project settings are quite vanilla and default.

Anybody seen this before?
Thank you!
