Node: Node 14.13 problematic (default?) import combinations

[arlac77]

There are some import combinations which do not work together any longer (each import alone works fine)

• Version:v14.13.0
• Platform: Darwin mbpMarkus 19.6.0 Darwin Kernel Version 19.6.0: Mon Aug 31 22:12:52 PDT 2020; root:xnu-6153.141.2~1/RELEASE_X86_64 x86_64
• Subsystem:

What steps will reproduce the bug?

import recast from "recast";
import lockfile from '@yarnpkg/lockfile';

How often does it reproduce? Is there a required condition?

Always (starting with node 14.13)

What is the expected behavior?

two default exports provided

What do you see instead?

node issue.mjs 
node_modules/recast/lib/lines.js:580
    assert_1.default.ok(tabWidth || tabless, "No tab width specified but encountered tabs in string\n" + string);
                     ^

TypeError: assert_1.default.ok is not a function

/cc @nodejs/modules

I verified this can be reproduced in v14.13.0 while it works in v14.12.0.

Reverting https://github.com/nodejs/node/pull/35249 fixes it.

[targos]

The TypeError: assert_1.default.ok is not a function error is thrown because in node_modules/recast/lib/lines.js, require('assert') returns an empty object instead of the assert module.
