Jupyter on VSCode takes >10 seconds to activate a kernel

[marceloprates]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.94.2

• OS Version: Ubuntu 22.04.5 LTS

• Conda 24.5.0

• Loading jupyter kernels started taking too long (>10s).

• I already checked and the problem doesn't seem to be related to jupyter itself, since kernels take about 1 second to run using jupyter outside vscode

• It also doesn't seem to be related with anaconda (I reinstalled it, tested different environments)

• It also takes too long to load venv environments, but loads the default python version (/usr/bin/python) very fast

Steps to Reproduce:

1. Install the jupyter extension
2. Create a blank conda environment with conda env -n test python==3.10
3. Install ipykernel with conda install ipykernel
4. Create a jupyter notebook, select kernel "test" and run the first cell
