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

  1. Install extension update 2.1.258
  2. Restart the extension (or reload VS Code window)
  3. 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
