Hey, thanks for the report. I can see in the screenshot that the .ipynb file opens, but the content is blank. This is a known issue on Windows after updates, try these in order:

  1. GPU rendering, often helps on Windows:
    Open or create %AppData%\Cursor\User\argv.json and add:
{
    "use-angle": "gl"
}

Restart Cursor.

  1. Start without extensions:
    Close Cursor, then run this in Command Prompt:
"C:\Program Files\Cursor\Cursor.exe" --disable-extensions

If the files load, one of the extensions is causing it, especially Jupyter-related extensions.

  1. Clear workspace cache:
  • Close Cursor
  • Go to %AppData%\Cursor\User\workspaceStorage
  • Delete the folder for this project, back it up first
  • Reopen Cursor
  1. Full reinstall:
    If nothing helped, download the latest installer from https://cursor.com and reinstall.

Also, please share logs from the Developer Console: Help > Toggle Developer Tools > Console tab. If you see red errors there, it’ll help narrow down the cause.

Let me know what worked.
