Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. It looks like the app starts and logs in, but it doesn’t get to loading the UI. This can sometimes happen because of stuck saved state that survives a reinstall. Let’s confirm and try a workaround.

First, a couple questions about what exactly happens on launch:

  • Does nothing show up at all, an empty window, an error dialog, or does the Agents Window open but stay empty?
  • In Task Manager after launch, do you see any Cursor processes still running?

Now the main test. Fully close Cursor first, kill all Cursor processes in Task Manager, then rename the folder %APPDATA%\Cursor to %APPDATA%\Cursor.bak and launch Cursor again. If Cursor opens after that, the cause is saved state in that folder, it isn’t removed during reinstall. Don’t delete Cursor.bak. If this works, we’ll need it for diagnostics.

A couple more things if it doesn’t help:

  • Try running the binary directly: %LOCALAPPDATA%\Programs\cursor\Cursor.exe
  • Collect logs from %APPDATA%\Cursor\logs the newest session folder, and attach them here

Let me know what worked and we’ll know where to dig next.
