Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the detailed report with logs.

I can see two issues right away:

  1. Extension host timeout (main issue)
  2. SQL error “Invalid column name ‘is_active’” which points to a corrupted workspace database

Try this order:

  1. Clear the workspace database (this will likely fix the SQL error):
  • Fully quit Cursor
  • Delete or rename this file: C:\Users\[your username]\AppData\Roaming\Cursor\User\globalStorage\state.vscdb
  • Restart Cursor (you’ll need to log in again)
  1. If that doesn’t help, check Git:
    The extension host often crashes if Git isn’t installed:
  • Open Command Prompt and run git --version
  • If Git isn’t found, install it from Redirecting…
  • Fully restart Cursor
  1. If it still doesn’t work, try a downgrade:
    Version 2.4.14 was broken (based on other reports), and 2.4.23 may also have issues. Download a previous version from Download · Cursor (scroll to “Previous versions” at the bottom).

Let me know if any of this helps. If not, please share:

  • Your exact Windows version (from About Windows)
  • The output of git --version
  • Rough project size (file count, and whether you have large node_modules)

Thank you for your answer.
I installed some random of recommended extension then problem solved.
By the way this error “Invalid column name ‘is_active’ ” was my prompt not an error that Cursor was showed.

Thanks for the update, glad you were able to fix it!

Most likely installing the extension helped restart the extension host properly. This is a known issue, sometimes the extension host doesn’t initialize correctly on Windows after installation.

Let me know if it comes up again.
