Cursor Not Working: Fixes for the Most Common Errors

When Cursor stops working, the most common causes are a failed AI model connection, an expired API key or subscription, a corrupted extension state, or a VS Code compatibility issue. Start by checking your Cursor account status at cursor.com, then reload the window with Ctrl+Shift+P → Reload Window. Most Cursor issues are resolved by signing out and back in or reinstalling the app.
