Can't queue multiple cells

[im-keiran]

Type: Bug

This bug is atrocious! I open a notebook, start shift-return'ing my way through the cells, and get this error:

notebook controller is DISPOSED.

Disabling the Python Environments extension helped for me: #16573 (comment)

EDIT: But it still happens after every kernel restart. I have to reload window to get it working again.

@im-keiran @teriik can you list the Extensions you have installed. In the past we've found that extensions like Continue and few others cause this issue.
Easy way to verify if to ensure you have just the Microsoft extensions installed (Jupyter, Python(s), Notebook Renderers)
Try this and let me know, if you still run into this please share you logs
Please could you enable logging as follows:

• Open settings & go into Jupyter->Logging
• Change the value to trace
• Reload VS Code,
• Attempt to repro the issue & then copy the output from the Jupyter output panel (use the command Jupyter: Show Output to get to the logs).

EDIT: But it still happens after every kernel restart. I have to reload window to get it working again.

@teriik Do you mean you still run into this with Python Env extension disabled?
