debug cell in jupyter notebook never executes or reaches breakpoint

See original GitHub issue

Issue Type: Bug

The debug cell feature has stopped working in jupyter notebooks, while still working in python scripts. I’ve observed this with different breakpoints in different source files.

For jupyter cells, the execution just hangs with the options to step over, step into… etc grayed out. Only options to pause, reset, and disconnect debugger are available. Upon disconnecting, nothing is output from the cell. Screenshot from 2022-03-02 11-43-42

Additionally I’ve noticed that sometimes when the notebook is first opened there is no option to debug the cell. After executing the cell, the option appears. Screenshot from 2022-03-02 12-15-34
