File mode specification error: (file-missing Doing vfork No such file or directory)

[dfrkp]

Hi! Thank you for this great package! Unfortunately it has stopped working for me:

Issue Description

When I open up any ipynb file emacs drops me in fundamental mode with this error message:

File mode specification error: (file-missing Doing vfork No such file or directory)

Environment:

MacOS 14.6.1
GNU Emacs 29.4 (build 1, aarch64-apple-darwin21.6.0, NS appkit-2113.60 Version 12.6.6 (Build 21G646)) of 2024-08-02

Config:

(use-package code-cells
  :ensure t
  :after python
  :hook (python-mode . code-cells-mode-maybe)
  )

Note: I do use python-ts-mode and eglot, not sure if there's a connection.
