Jupyterlab Code Formatter generates errors at Jupyterlab start: "Uncaught exception" and "FileNotFoundError"
After starting JupyterLab a error is generated by Jupyterlab Code Formatter.
What does the "uncaught exception" and "FileNotFoundError" mean? I cannot identify a file that should be found.
See following log:

Hello, I don't use Windows so I can't really test things out.
Can you in a WinPython interpreter try using subprocess.Popen? I have a feeling WinPython has implemented subprocess.Popen in way that breaks this plugin.
Hi @ryantam626,
I tried the example from the first note under the definition of subprocess.Popen in a WinPython interpreter. It failed. Here is the output.
>>> import shlex, subprocess
>>> command_line = input()
/bin/vikings -input eggs.txt -output "spam spam.txt" -cmd "echo '$MONEY'"
>>> args = shlex.split(command_line)
>>> print(args)
['/bin/vikings', '-input', 'eggs.txt', '-output', 'spam spam.txt', '-cmd', "echo '$MONEY'"]
>>> p = subprocess.Popen(args)

I set up a new python on my computer, the same error occurs when using miniforge python. Here is the log. Any ideas?

Hi! Can you try it with the latest version of the plugin (1.5.3)? It includes a change that should fix this issue.
