Hey, thanks for the report. This is an expected change in the latest update. Cursor now opens the Agents Window on startup.
To switch back to the Editor Window by default: Cursor Settings > Agents > turn off Open Agents Window on startup.
You mentioned you think you already set it, but it’s not working. If the toggle is off and Cursor still starts in the Agents Window, please confirm. That would be a separate bug with the toggle itself, and I’ll log it with your details. While it’s being fixed, you can switch via Ctrl+Shift+N or Command Palette Ctrl+Shift+P > Open Editor Window.
Let me know if that helped, and whether the toggle stays off after restart.
