What's Wrong?

Bug: Claude Code 2.1.53 fails to activate on Windows due to hardcoded Linux path

Version: anthropic.claude-code-2.1.53-win32-x64

OS: Windows

Description:
The extension fails to activate on Windows with the following error:

TypeError: The argument 'filename' must be a file URL object, file URL string, or absolute path string.
Received 'file:///home/runner/work/claude-cli-internal/claude-cli-internal/build-agent-sdk/sdk.mjs'

It appears the extension was built on a Linux CI/CD runner and a hardcoded Linux path (/home/runner/work/...) was embedded into extension.js. This path is invalid on Windows, causing the extension to crash immediately on activation.

As a result, all chat sessions fail to load and the extension is completely non-functional on Windows.

Steps to reproduce:

1. Install Claude Code 2.1.53 on Windows
2. Open VSCode
3. Extension fails to activate

Expected behavior: Extension activates normally.

Actual behavior: Extension crashes with the Linux path error above. All chat sessions show "Error providing chat sessions: Canceled".

What Should Happen?

Expected behavior:
The extension should activate successfully on Windows and all chat sessions should load normally.
