Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
Run / Play button for Python file disappeared from editor tab after recent update
Steps to Reproduce
Open Cursor on Windows 11.
Create or open a simple Python file, for example run_editor.py with print(“test”).
Look at the top of the editor tab where the Run (Play) button normally appears.
The Run button is missing and there is no way to run the file from the editor header.
Expected Behavior
For Python files, there should be a Run (Play) button in the editor tab/header so I can run the current file with one click, as it worked before the recent update.

Additional Information
The issue happens in all workspaces and for any .py file I open.
It started recently (most likely after an update).
I haven’t changed my Python or run configuration manually before the button disappeared.
Does this stop you from using Cursor
No - Cursor works, but with this issue
