Description

Hi. I tried running jupyter notebook recently and faced with the following issue. I run local jupyter server, try to open any notebook from filesystem and I get 500 : Internal Server Error.

Here are logs from jupyter server.

Reproducer

I installed jupyter with the following steps.

sudo pip3 install virtualenv
virtualenv env
source ./env/bin/activate
pip3 install jupyter

Context

Operating System and version: Linux Ubuntu 20.04.3

When faced issue for first time tried to google it. Found a recommendation to update pygments to >=2.4.1. Did pip3 install --upgrade pygments. Didn't help. Also tried to update nbconvert. Didn't help as well.
Here is the list of packages in pip3:
