Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. The Connection stalled error in runAgentLoop is a known issue in version 2.4.21, and the team is investigating it. A few users have reported this over the last few days.

Related reports: Connection Error / Stalled Agent requests for hours - #9 by Fares_Bendhiab

Try this workaround that helped other users with the same stack trace:

  • Fully quit Cursor Cmd+Q
  • Rename your project folder in Finder (for example MyProject → MyProject_v2)
  • Open the renamed folder in Cursor

If that doesn’t help, try switching to the Stable channel: Cursor Settings > Beta > Stable > Restart.

Keep an eye on updates in the linked thread.
