Environment Information

System: Windows 10
Node.js version: v14.18.1
Chrome version: 96.0.4664.55

Provide the steps to reproduce

When I use custom userDataDir, and remove it after chrome exit.

const customUserDataDir = 'D:\\.browser-temp\\chrome-4f32efbed74f445c';

const chrome = await launch({
  userDataDir: customUserDataDir
});

chrome.process.on('close', () => {
  if (fs.existsSync(customUserDataDir)) {
    const rm = fs.rmSync || fs.rmdirSync;
  
    rm(customUserDataDir)
  }
});

What is the current behavior?

(node:3204) UnhandledPromiseRejectionWarning: Error: EPERM: operation not permitted, unlink 'D:\\.browser-temp\\chrome-4f32efbed74f445c\\chrome-err.log'

What is the expected behavior?

The outFile and errFile should be handled by fs.closeSync when chrome exit.
