**How severe does this issue affect your experience of using Ray?**

- High: It blocks me to complete my task.

i am a newbe in ray and had setup a small script on my laptop and started trying out ray. I ran a sample script like below and it was working fine. Now, today morning, all of a sudden, the ray.init() has started giving me below error. What changed overnight and how to resolve this? I had to show a demo to my team and this started coming up. This is happening with all my ray scripts.

can you try spinning up a hosted anyscale workspace and see if you can repro; it has some free trial credits through in and quickly helps troubleshoot whether this is infra level versus a ray issue.

hosted anyscale is great for this as it gives you a jupyter notebook experience to quickly validate ray logic in a controlled environment where all of the infra level is already taken care of/set up right for you.

you can sign up at [anyscale.com](http://anyscale.com) \> slack me on Ray Slack as well and we can debug together.

i tried to clear the %temp%/ray folder and the issue is resolved.
