process-live-p fails on MacOS Catalina

[bibekpokharel]

After debugging previously, the current version was stable on my computer until I updated both to Catalina and the new version of emacs-jupyter. The error I get when I try to execute a simple python command is

executing Python code block (packages)...
Starting py kernel process...done
cl--assertion-failed: Assertion failed: (process-live-p process)

Evaluating (jupyter-completing-read-kernelspec) works fine and I can find my jupyter kernels. Perhaps jupyter is failing to start? I am unsure whether the issue lies with Mojave or with the emacs-jupyter.

Can you evaluate (setq jupyter--debug t), try again, and then show the messages produced in the *Messages* buffer.

Here I get the same error. At first, when I start the jupyter-repl for Julia it works, but after a short period, I would get the error. Also, I don't get this error with the python repl. Here is the message with jupyter debug set to true
