Description
After updating the Claude Code VS Code extension from 2.1.257 to 2.1.258 and restarting extensions, the extension stopped responding. Submitting a prompt showed a loading/thinking spinner that never completed or timed out.
Environment
- Extension: anthropic.claude-code
- Broken version: 2.1.258
- Last known working version: 2.1.257
- VS Code version: 1.135.0 (08d4889f9ec4a1685d257b9b95de036c8e1ce1e5, x64)
- OS: Windows 11 Enterprise 10.0.26200
Steps to reproduce
- Install extension update 2.1.258
- Restart the extension (or reload VS Code window)
- Send any prompt to Claude in the extension
Expected behavior
Extension responds to the prompt as normal.
Actual behavior
Spinner/loading indicator gets stuck indefinitely; no response is ever returned.
Workarounds attempted
- Restarted just the extension — did not resolve it
- Fully restarted VS Code — did not resolve it
- Reverted extension to 2.1.257 — this resolved the issue and the extension works normally again
