Hi Nadya,

This is a known issue we’re actively tracking. It’s client-side — your account/subscription are fine.

One quick note: you mentioned v2.6.18, but your version block shows v2.4.23 (after the downgrade). Either can be affected, especially since workspace state can persist across version changes.

Since you’ve already tried disabling extensions and clearing cache, here are the next steps (in the order most likely to help):

  1. Close all chat tabs + start fresh - On Windows, some chat tabs (especially ones involving file changes) can balloon memory and freeze the whole IDE.

    a. Close every chat tab
    b. Open new chats going forward
    c. If opening a specific chat re-freezes Cursor, delete that chat

  2. Reset the workspace state DB - This is separate from the general cache and often fixes persistent hangs.

    a. Fully quit Cursor
    b. Delete/rename:
    C:\Users\<you>\AppData\Roaming\Cursor\User\globalStorage\state.vscdb
    c.Relaunch Cursor (you’ll need to sign in again)

  3. Update to the latest Cursor
    Several Windows performance + stability fixes have shipped since 2.4.x.

  4. Disable HTTP/2 (if not already)
    Settings → search cursor.general.disableHttp2 → set to true → restart

  5. Clean reinstall (last resort)
    Reinstall Cursor after deleting %APPDATA%\Cursor(to remove all leftover state)

If it’s still happening, can you share:

  • Help → About output (after updating)

  • Whether closing chat tabs reduced the slowness at all
