[BUG] [URGENT!!!] Claude Code is hanging / freezing / stuck on heaps of prompts for 5-20minutes or more.

### Preflight Checklist - [x] I have searched [existing issues](https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20state%3Aopen%20label%3Abug) and this hasn't been reported yet - [x] This is a single bug report (please file separate reports for different bugs) - [x] I am using the latest version of Claude Code ### What's Wrong? Ever since the release of Opus 4.6 at least, and maybe slightly before (I can't remember exactly when it started), Claude gets stuck "thinking" for ~5-20 minutes, and sometimes even longer. Token usage does not go up during this time, and packet inspection shows it hanging on waiting for SSE events from Anthropic end for the given prompt. Sometimes this can be fixed by sending a follow up prompt (doesn't matter what it contains), that kicks it back into action and allows the "thinking" prompt to start flowing again. Other times that doesn't work either. This isn't Claude doing things behind the scenes, it's literally just stuck / blocking, and doing nothing at all. In most cases, EVENTUALLY, it seems to unfreeze itself, somehow. But it tends to take over 5 minutes, sometimes beyond 20 mins. Theres a lot of other people complaining of similar problems, and I'm sure it is affecting a very large amount of users, but I haven't seen any evidence to see Anthropic is aware of it. ### What Should Happen? Not freeze. ### Error Messages/Logs ```shell ``` ### Steps to Reproduce I'm not sure how to trigger it deterministically. ### C
