• VS Code Version: 1.63.2
• OS Version: Windows 11

Steps to Reproduce:

1. Create notebook
2. Select kernel and write code/run cells
3. Save notebook
4. Kernel selection disappears

I started working on an analysis and when I got to a checkpoint I was happy with I saved the notebook. After saving I tried to keep working and started getting errors in my notebook and it took me a few minutes to realize the kernel was not saved so I had to select it again and rerun everything to get back to where I was, a pretty annoying papercut
