Timed out resolving AVA configuration

Error message

Timed out resolving AVA configuration

What it means

Thrown by resolveGlobsSync when the Atomics.wait on the worker's shared synchronization buffer returns 'timed-out' — no signal arrived within 10 seconds. It means the eslint-plugin-helper worker thread never delivered its computed glob results: the worker crashed, hung while loading the ESLint config (e.g. plugins resolving over the network), or was blocked before writing to the shared buffer.

Solutions

1. Verify the AVA/ESLint configuration in projectDir loads quickly and does not await network resources or long-running plugins
2. Run the worker script (lib/eslint-plugin-helper-worker.js) directly to surface a hidden worker-side crash
3. Check that workerData buffers and the firstMessage payload are valid for the current AVA version; reinstall or upgrade AVA
4. Increase the 10_000 ms Atomics.wait timeout locally if configs are legitimately slow, or precompute the config outside the worker
