Hey, thanks for the report. It looks like a known freeze issue in 2.1.39-2.1.46 on Windows. Let’s quickly narrow down the cause:
Please attach:
- Screenshot of Settings > Network > Run Diagnostics
- Request ID from the frozen session (chat menu icon > Copy Request ID)
- Console errors: Help > Toggle Developer Tools > Console (open before reproducing)
- Screenshot of
CTRL+Shift+P> Developer: Open Process Explorer (what’s eating CPU/RAM during the freeze) - Indexing panel status (green/error?) and if there are MCP servers in Settings (temporarily disable them)
Try:
- VS Code Settings > search “HTTP/2” > enable “Disable HTTP/2”
- Disable MCP servers (if any) and restart
- Close all open tabs/files and restart (this helped here: Cursor app becomes unresponsive and crashes after opening a project)
- Check Indexing: if there’s an error/“Initializing…”, try opening a smaller subfolder of the repo (see cases: The Cursor IDE freezes at the "planning next moves" stage)
Relevant threads we’re working on:
- Final Review step/freeze: Cursor freezes on final “Review Changes” step in Agent Mode
- Planning/hanging: Cursor is unresponsive after sending a prompt to plan
Send the artifacts above - I’ll assign to engineers and prioritize. Let me know if this helps.
