There is something wrong with my VScode after it upgrades to 1.5.1 its self

My Jupyter Notebook cannot run in my VScode after it automatically upgrades to 1.5.1 version. It says

Using the Jupyter notebook editor requires the stable version of VScode
and the CustomEditor experiment to be enabled.

I am not sure what's wrong with version 1.5.1 of VScode.

And I do not know how to let the 'CustomEditor experiment' to be enabled.
