No module named 'nbformat'

Bug description

First of all I want to clarify that this is my first post here, I apologize if it's not completely clear.

Once I got to know Quarto I wanted to start experimenting with it working with Python, however, I have not been able to because the nbformat package is not installed. However, when I check the list of installed packages this package appears there in both the conda and pip package lists. Can anyone tell me what the problem is? I have tried RStudio and VS code but I have the same issue with both.

OS: Ubuntu 20.04.4 LTS
RStudio Version: 2022.07.1
VS code Version: 1.70.1

Console output when I want to Render the document:

(base) ..$ quarto preview quarto_test.qmd --to html --no-browser --no-watch-inputs

Quarto

Quarto enables you to weave together content and executable code into a finished docquartoument. To learn more about Quarto see https://quarto.org.

Running Code

When you click the Render button a document will be generated that includes both content and the output of embedded code. You can embed code like this:

1 + 1

You can add options to executable code like this

#| echo: false
2 * 2

The echo: false option disables the printing of code (only output is displayed).

Start by reproducing the reported quarto preview command and compare the Python interpreter used by Quarto with the environment where nbformat is installed. Inspect /opt/quarto/share/jupyter/jupyter.py and notebook.py, using the quarto check output as context. Done means the reported environment mismatch is understood and the Jupyter render either succeeds or produces a clear diagnostic.
