Environment

The jiti version is 2.5.0.

Noticed in a Ubuntu VM running Node.js 24.4.1, but I can reproduce it in older versions, too.

Reproduction

A minimal repro:

// index.mjs
import { createJiti } from 'jiti';

const jiti = createJiti(import.meta.filename);
const ctsFileURL = new URL('./file.cts', import.meta.url);
await jiti.import(ctsFileURL.href);

// file.cts
export = Promise.resolve({});

Running node ./index.mjs prints:

TypeError: Method Promise.prototype.then called on incompatible receiver #<Promise>

Also a StackBlitz repro: https://stackblitz.com/edit/hffiw6dx

Describe the bug

It seems that a recent change in jiti v2.5.0 is causing an error when a CommonJS module that export a Promise is imported.

Additional context

We noticed that jiti v2.5.0 is causing CI failures in the ESLint repo, for example: https://github.com/eslint/eslint/actions/runs/16488422115/job/46617784304.
