WebSocket is not defined

Hi,

I'm currently facing an issue with Jupyter in VSC. When I try to run a cell, I encounter the following error:

category: 'unknown',
isJupyterError: true,
originalException: [ReferenceError: WebSocket is not defined

I reinstalled VSC, reinstalled Python, deleted all requirements and reinstalled them and the issue persists. The strange thing is that jupyter is working outside VSC!
