Describe the bug

Apologies beforehand, vague bug report incoming...

As of a recent Vitest update (potentially between v3.1.4 and v3.2.3) we're seeing the following error in CI, where it appears the channel is closed before our tests have finished running:

⎯⎯⎯⎯ Unhandled Rejection ⎯⎯⎯⎯⎯
Error: Channel closed
 ❯ target.send node:internal/child_process:753:16
 ❯ ProcessWorker.send ../../node_modules/tinypool/dist/index.js:140:41

 ❯ [nodejs.internal.kHybridDispatch] node:internal/event_target:831:20

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
Serialized Error: { code: 'ERR_IPC_CHANNEL_CLOSED' }

Opening this issue hoping that maybe someone could point me in the right direction.
