Hey, thanks for the report. I’ll go through each item:

  1. “Extension host is not running”
    A few things to try:
  • Run from the command line with cursor --disable-extensions , does the error still show up?
  • Open Help > Toggle Developer Tools > Console before the error happens, then share any red errors you see there
  • Try deleting the state database: %APPDATA%\Cursor\User\globalStorage\state.vscdb (you’ll need to sign in again after this, so please back it up first)
  1. Diffs don’t show after the agent makes changes
    This is a known issue in 2.5.x. A lot of users have reported it. Main thread here: Only some diffs are shown when agent makes changes

The team is aware. For now, please use the Review button in the chat panel to see all changes. It’s not perfect, but it works as a temporary workaround.

  1. Delays and lag while the agent is making changes
    To narrow it down:
  • How big is your project (rough number of files)?
  • Ctrl+Shift+P > Developer: Open Process Explorer, what uses the most CPU or memory when the lag happens?
  • Do you have a lot of extensions installed?
  1. Terminal errors (PowerShell / sandbox)
    I can see errors in your screenshot: sandbox: warning - direct egress blocking is best-effort on Windows, a symlink error, and Cannot bind argument to parameter 'Command' because it is an empty string. This is a known issue with sandbox on Windows plus PowerShell. A similar issue is described here: Cannot run any commands due to sandbox on windows in 2.5

Workaround:

  1. Cursor Settings Ctrl+Shift+J
  2. Agents > Auto-Run in Sandbox > turn it off
  3. Agents > Legacy Terminal Tool > turn it on
  4. Ctrl+Shift+P > Terminal: Kill All Terminals
  5. Fully restart Cursor

Commands will ask for confirmation instead of auto-running, but they should run without sandbox errors.

Let me know how it goes.
