Expected behavior

A small drop down arrow next to the run cell, which shows a debug cell option:

Actual behavior

The drop down arrow disappears after a single debug run, and using the ctrl + shift + alt + enter to key combo to debug the cell is also unresponsive. Sometimes it comes back in a few minutes of waiting and sometimes I have to restart VS Code.

Steps to reproduce:

1. Start a notebook
2. Debug a cell
3. The down arrow disappears.

Logs

Facing the same issue on mac os

jupyter version: v2022.11.1003412109

For me, It happens after my debugger crash and I force close the debugger.

1. Try restarting the notebook doesn’t work.
2. Restarting vscode could solve the problem

Having same issue on 1.68.1. Intermittent but usually happens after a debug crash. Scrolling doesn’t help but running some other cell usually brings back the fantom debug option. In one worse case where it didn’t reappear - only a restart of vscode worked.
