Python 3.12.3

Describe the issue:

When attempting to render a qmd document using the jupyter engine from about 1 in 5ish of the times the following error will occur:

Starting python3 kernel...ERROR: 

[Errno 2] No such file or directory: 'Lec25_stan.quarto_ipynb'

After the error it is possible to immediately attempt to re-render and the issue will go away and the document will successfully render.

This is a new issue with this release, using the same documents I was not seeing this behavior with the previous release.

Steps to reproduce the issue:

1. Repeat a regular workflow with a jupyter qmd document and attempt to regularly re-render as you update the document.

Expected or desired behavior:

Were there any error messages in the UI, Output panel, or Developer Tools console?

Not that I can find

Start by repeatedly rendering a Jupyter-engine qmd document with Python 3.12.3 on Positron 2025.04.0, capturing the available Output panel and Developer Tools logs for failing and successful runs. The work is done when repeated renders no longer intermittently report the missing .quarto_ipynb file and the document renders successfully.
