[BUG] Claude Code freezes during thinking or at a random token while still consuming usage limits

What's Wrong?

Claude Code sometimes freezes halfway through a response - either during the extended thinking phase or on a random token - and completely stops generating output. Despite no visible activity, it continues to consume tokens and user limits. The only workaround is CTRL+C and resending the prompt.

Environment

System: Windows 11
Installation method: native installer (irm https://claude.ai/install.ps1 | iex)
Model: claude-sonnet-4-6 (default)

What Should Happen?

Expected behavior

Claude Code should either complete the response or return a timeout/error and stop consuming limits. In its current state, this can be perceived as misleading for users. Claude experiences failures relatively often, and users receive no compensation, which may be considered an unfair practice.

Actual behavior

The process stalls, does nothing, and tokens/limits continue to be consumed. No error message is shown.

Steps to Reproduce

1. Run Claude Code on any project (e.g. C# code analysis)
2. Send any prompt
3. Claude freezes on a random token

Is this a regression?

Yes, this worked in a previous version
