useMemoCache is not a function on Vercel with Next Canary

[Dan6erbond]

Describe the Bug

I'm on the Next canary branch, and after figuring out how to get Payload to work with dynamicIO enabled once my app is deployed on Vercel I see this error in the logs:

⨯ TypeError: n.H.useMemoCache is not a function
    at W (.next/server/app/(payload)/admin/[[...segments]]/page.js:81:5202) {
  digest: '1619017580'
}

I've tried enabling/disabling the React compiler since it seems useMemoCache is a replacement function it creates, but that didn't help. I also tried using annotation mode to make the compiler opt-in.

Reproduction Steps

1. Install dependencies with pnpm i
2. Copy .env.example to .env
3. Start Postgres using Docker compose
4. Build the app with pnpm build
5. Start the server with pnpm start
