Workaround

Add a delay of 5 seconds before goto (the error appear with lower seconds)

import { setTimeout } from 'node:timers/promises'
...
// Add delay of 5 seconds
await setTimeout(5000)
await page.goto('<URL>')

It has been tested many times with the test file and there are no issues with Cloudflare WAF and Turnstile. There may be a momentary problem with the proxy you are using or your network. If the issue can be reproduced, please report it via this thread. Thank you.
