Hey, thanks for the report. This is a known issue where the agent hangs on the client side after the backend has already processed the request.

You are on Windows 11 Insider build 26200. A user on the same build Waiting for extension host - blocking error had this issue and fixed it by moving heavy directories like node_modules, build artifacts, and a large .git history outside the workspace.

Please try this:

1. Check your workspace for heavy directories. Move them out or add them to .cursorignore.

2. Disable HTTP/2. Add this to settings.json via Ctrl+Shift+P then Preferences: Open User Settings (JSON):

   "cursor.general.disableHttp2": true
   

3. Reindex the project: File → Preferences → Cursor Settings → Indexing & Docs → Reindex.

4. Keep chats short. Long threads with 100+ messages can trigger hangs, so start a new chat more often with Ctrl+N.

5. Run network diagnostics: Cursor Settings → Network → Run Diagnostics. Send a screenshot if it still does not help.

Another similar thread with workarounds: AI messages are freezing/hanging during sending

Let me know what worked.
