[Bug]: Jest v29 error with Babel, Yarn v3: Jest worker encountered 4 child process exceptions, exceeding retry limit

Version

29.1.1

Steps to reproduce

Clone my repo at https://github.com/jgerigmeyer/jest-test
Use Node v16.17.1
yarn install
yarn test

See the error:

Error: Jest worker encountered 4 child process exceptions, exceeding retry limit
    at ChildProcessWorker.initialize (/.../jest-test/.yarn/cache/jest-worker-npm-29.1.0-68250d556a-8ff2ce6026.zip/node_modules/jest-worker/build/workers/ChildProcessWorker.js:211:21)
    at ChildProcessWorker._onExit (/.../jest-test/.yarn/cache/jest-worker-npm-29.1.0-68250d556a-8ff2ce6026.zip/node_modules/jest-worker/build/workers/ChildProcessWorker.js:396:12)
    at ChildProcess.emit (node:events:513:28)
    at Process.ChildProcess._handle.onexit (node:internal/child_process:291:12)

yarn test -i

No error:

Expected behavior

I expect the test to pass.

Actual behavior

Error: Jest worker encountered 4 child process exceptions, exceeding retry limit
    at ChildProcessWorker.initialize (/.../jest-test/.yarn/cache/jest-worker-npm-29.1.0-68250d556a-8ff2ce6026.zip/node_modules/jest-worker/build/workers/ChildProcessWorker.js:211:21)
    at ChildProcessWorker._onExit (/.../jest-test/.yarn/cache/jest-worker-npm-29.1.0-68250d556a-8ff2ce6026.zip/node_modules/jest-worker/build/workers/ChildProcessWorker.js:396:12)
    at ChildProcess.emit (node:events:513:28)
    at Process.ChildProcess._handle.onexit (node:internal/child_process:291:12)

Additional context

The error is inconsistent, and does not occur on every run. Possibly something to do with memory availability? On a large project with lots of tests, the error seems to occur consistently. On a small sample repo I get it most often right after a fresh yarn install. 🤷

@ericvera Thanks! I still get the error (with no helpful info) with --maxWorkers=2, but your packageExtensions solution also fixed it for me. 👍
