Debugging doesnt work in Python 3.10.2 (breakpoint ignored)

[danieltomasz]

This is discussed here in the context of vscode-jupyter extension microsoft/vscode-jupyter#8803
it doesn't work in kernel with 3.10.2 when debugging both VSCode and Jupyter Lab (callstack is empty, Jupyter 3.2.9)
When coming back to 3.9.10 everything is ok

I used pyenv virtualenv pyenv install 3.10.2 and makefile to create separate environment

.ONESHELL:

.PHONY: install

PROJECT=debug
VERSION=3.10.2
VENV=${PROJECT}-${VERSION}
VENV_DIR=$(shell pyenv root)/versions/${VENV}
PYTHON=${VENV_DIR}/bin/python

install:
	@echo "Installing $(VENV)"
	pyenv virtualenv ${VERSION} ${VENV}
	pyenv local ${VENV}
	$(PYTHON) -m pip cache purge 
	$(PYTHON) -m pip  install -U pip
	$(PYTHON) -m pip install wheel
	$(PYTHON) -m pip install ipykernel
	$(PYTHON) -m ipykernel install --user --name ${VENV}

Code used for debugging in Jupyter Notebook

# count the number of mouse in list of devices
devices = ['laptop','mouse', 'mouse', 'charger', 'mouse', 'keyboard', 'mouse']
mouse_count = 0

for device in devices:
    if device.upper() == 'MOUSE':
        mouse_count += 1

print(f"mouse count : {mouse_count}")

I check with the latest git main branch and it doesn't work too

I am on MacOS 12.3 (M1)
