[BUG] Claude Code vscode extension on Windows keeps working but nothing is happening

[umstek]

Preflight Checklist

• I am using the latest version of Claude Code

What's Wrong?

Windows 11, vscode extension with latest Claude code. vscode was open, and I came back after a few hours after a break. I entered a prompt but it keeps running without doing anything.

It seems to be working, but nothing happens. No error, no timeout. I looked at the usage tab (web) as well, and it is not consuming tokens either. And I cannot even stop it. This is not the first time it happened, and it is annoying.

However, claude with terminal works.

What Should Happen?

It should work normally

same issue!
It is a NIGHTMARE!
it was working fine. then windows HAD TO DO THEIR UPDATE on my PC. Kept getting those annoying reminders. I finally accepted to do the update, and NOTHING with Claude in VSC has worked since. Microsoft completely fucked me (and everyone else it seems too). SUPER PISSED

[gKochmann1975]

feedback i got:
Before the Windows update, you had an older version of the Claude Code extension that worked. When Windows broke everything and we had to reinstall, you got the latest version (2.1.31) which has this Windows bug.
The bug isn't in YOUR setup — it's in the newer extension code. Anthropic broke something in their own update and hasn't fixed it yet.
It's the same thing Microsoft did to you — a software update broke something that was working fine. Except this time it's Anthropic's update, not Microsoft's.

[gKochmann1975]

install a previous version of a VS Code extension.DoneIn VS Code you can install a previous version of any extension. Try this:

Go to Extensions sidebar (Ctrl+Shift+X)
Find Claude Code for VS Code
Click the gear icon ⚙️ next to it
Click "Install Another Version..."
Look for a version from around late January when it was working for you — try something like 2.1.7 or earlier

That should roll you back to the version that was working before. Do NOT let it auto-update after that — you can disable auto-updates for this extension by clicking the gear icon again and selecting "Disable Auto Update".
