Environment

OS: Windows 11 Home 10.0.26200
Claude Code: v2.1.143 (latest)
Shell: PowerShell / Bash

Bug

Edit and Write tools hang silently — no error, no output, no file changes.
Sessions freeze for 30+ minutes until manually stopped. On retry, sometimes
succeeds, mostly fails again.

Bash-based file operations (node, printf, sed) succeed on the same files.

Steps to reproduce

Open any project on Windows 11 with v2.1.143
Ask Claude to edit a file — Claude uses the Edit or Write tool
Session hangs indefinitely, no error surfaced — must force-stop manually

Expected

Edit/Write tools modify the file and return success.

Actual

Tool hangs silently. No error reported. File unchanged. Only recovery is
manual stop + retry (non-deterministic — sometimes works, usually doesn't).
Bash workarounds work reliably.

Note

Issue #46767 describes a similar bug from April (v2.1.101). This appears to be
a regression or continuation of that bug in the latest release.

Not a duplicate. #59200 is about tool result delivery failing for Bash/PowerShell calls. This issue is specific to the Edit and Write file-editing tools hanging silently. Different tools, different code path.

Fixed in v2.1.146 — Edit and Write tools work normally again on Windows 11.

I wouldnt say this is closed, I've been experiencing exactly this intermittently for weeks. I've let it run for over an hour and still had to cancel it myself and it's done edits/writes via powershell script instead, but this tanks my quota quicker / builds context faster. v2.1.190.
