The bug report is here: https://github.com/python/cpython/issues/44604
However, the users who have posted thus far only reference a workaround for vs code:
@ewout, the current workaround (until pydevd is fixed) is to add -Xfrozen_modules=off to the Python command line.
There is also a reference to launch.json, which I assume is vs code configuration. What would be the equivalent in PyCharm? Thanks.
