NextJS 15: Error: react-dom/server is not supported in React Server Components

Issue:
This issue happen after I upgrade to nextjs lasted version (15.0.0-canary.195).
It throws this error when I create a new Resend instance:

new Resend(resendApiKey)

Error:

This might be an issue with React Email's render instead of with Resend, but I can't seem to reproduce in the way you said on a minimal project. Could you trim down the project you sent so that it's easier to run and so that I can reproduce?
