bash kernel dies in jupyter notebook

I am trying to use a bash kernel in jupyter notebooks and am receiving the following error:

Connection failed

A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration.

I have tried the following workflow.

From python command prompt:

conda create --name bash_env --clone arcgispro-py3 conda install -c conda-forge bash_kernel python -m bash_kernel.install

However, no matter what I try, I get a not connected error.

I'm on Windows 11.

jupyter kernelspec list returns:

.net-csharp C:\Users\myusername\AppData\Roaming\jupyter\kernels\.net-csharp .net-fsharp C:\Users\myusername\AppData\Roaming\jupyter\kernels\.net-fsharp .net-powershell C:\Users\myusername\AppData\Roaming\jupyter\kernels\.net-powershell bash C:\Users\myusername\AppData\Roaming\jupyter\kernels\bash javascript C:\Users\myusername\AppData\Roaming\jupyter\kernels\javascript python3 C:\Users\myusername\AppData\Local\ESRI\conda\envs\bash_env\share\jupyter\kernels\python3

kernel.json within the above bash location reads:

{"argv": ["C:\\Users\\myusername\\AppData\\Local\\ESRI\\conda\\envs\\bash_env\\python.exe", "-m", "bash_kernel", "-f", "{connection_file}"], "codemirror_mode": "shell", "display_name": "Bash", "env": {"PS1": "$"}, "language": "bash"}

(Note: I have tried multiple alterations to kernel.json, including pointing to bash.exe, none of which have worked). I've also deleted that entire bash directory so that it reads it from the bash_env and it still didn't work.

I have Git Bash downloaded and

where bash

run from Git Bash returns:

C:\Program Files\Git\usr\bin\bash.exe C:\Windows\System32\bash.exe

my bash_env python environment has:

jupyter_server 1.21.0 ipykernel 6.16.0 ipykernel 6.16.0 ipython 7.34.0

I have already tried to delete cookies.

The traceback within python command prompt is too long to paste, but here's a portion:
