vscode-jupyter: VSC fails to connect to (any) python kernel.

After the upgrade to the latest VSC version on Linux Ubuntu 20.04 I cannot run any jupyter notebook. When I run any cell, using any environment (that used to work till the previous version), VSC seems to fail connecting to the python kernel, a dialog shows up and says:

Connecting to kernel: base (Python 3.9.5): Activating Python Environment 'Python 3.9.5 ('base')'

It never disappears.

Expected behaviour

Cell is run.

Actual behaviour

Cell is never run, for every conda environment and kernel I can select, I read:

Steps to reproduce:

In my case it is enough to open any jupyter notebook, select any environemnt and run any cell.
