Hopefully nodejs/node#50825 should address this.

Is esmocha used to test a yeoman-generator fork only?
Fixing that node behavior is not enough fix tests.
The main problem is the mocking lib that needs major changes due to loader/main thread communication.
I plan to fix esmocha, but for yeoman-generator migrate to vitest is the best option.

Error disappeared with nodejs/node#50825.
