I have the same problem

[itsMapleLeaf]

I managed to reproduce this error minimally (repo). It occurs on namespace accesses from a module with export * as name from 'mod'

Example:

// mod.ts
export * as Mod from "./mod.js"
export type A = string

// index.ts
import { Mod } from "./mod"

type B = Mod.A

Doing the "Move to file" or "Move to a new file" refactors on type B produces this error:

Although this might hint at where the problem actually is, it's probably broader than this, because I'm seemingly hitting other cases that don't involve this 🤔

Minimal repro of the original issue:

// @allowjs: true

// @Filename: /start.js
//// // @ts-check

//// [|const startServer = require('./server.js');

// @Filename: /server.js

    newFileContents: {

`<div>a</div>;
`,
    }
});

@itsMapleLeaf https://github.com/microsoft/TypeScript/issues/59240#issuecomment-2224079385 should be fixed after https://github.com/microsoft/TypeScript/pull/60333. I think the case you repro-ed is similar to #58897, and is included in my PR.
