Emacs on windows locking up on "jupyter-org-restart-kernel-execute-buffer"

[alaskamike]

I've been using emacs-jupyter for about a month now. Recently (like in the last week or so) emacs has started hanging when I execute "jupyter-org-restart-kernel-execute-buffer". It seems to be related to the number of source blocks - one file I have with 101 jupyter-python blocks locks up every time I run it. I deleted about half of the blocks and sometimes it will run cleanly and other times it will lock up. I end up using the task manager to kill emacs and start over. I have also tried rapidly executing the blocks (shift-enter) and sometimes this will lock up too.

I am using emacs 27.2 with scimax, and python 3.7.9.

I've upgraded to emacs 28.2, and I still have the problem.
