What steps will reproduce the bug?
https://github.com/JounQin/test/tree/repro/node_require_resolve_paths
Simply run node test.js
On node 10:
`resolve` npm package: <CWD>/fixtures/bar.js
`require.resolve` built-in function: <CWD>/fixtures/bar.js
How often does it reproduce? Is there a required condition?
Persist
What is the expected behavior? Why is that the expected behavior?
There is a related old issue #29139.
What do you see instead?
On node 12+, of course including Node LTS (20+)
`resolve` npm package: /Users/JounQin/Workspaces/GitHub/test/fixtures/bar.js
node:internal/modules/cjs/loader:1404
throw err;
^
Error: Cannot find module 'bar'

Additional information
I believe there is no reports because most projects use http://npmjs.com/resolve instead, and it behaviors same as Node 10-, and I'm trying to remove resolve as dependency, so I just met this issue at https://github.com/un-ts/eslint-plugin-import-x/pull/272#issuecomment-2915145320

Research direction
Run the linked reproduction's test.js under Node 10 and Node 12+ and compare the require.resolve results when paths is supplied. Read the CommonJS loader path shown in the stack trace and related issue #29139; done means the reproduction resolves fixtures/bar.js consistently without the external resolve package.
