Thanks for filing this issue. I thought we had fixed this. Will double check.
I am now having the same issue but with original notebooks. Does not recognize a file that is in my directory no matter what I do with settings and manually changing the directories.

@rchiodo The message Could NOT open editor for .... seems to be related to some change you made recently (or was planning on making). I recall something about opening some editor (supporting some magic command)
Let me try this at my end.
%%edit
was the command I was talking about. That wouldn't impact this scenario.

settings.json & add the following:"python.logging.level": "debug"Python & Jupyter output panels & paste them hereAlso, please copy output from Console window.
I would like to see the details of the error you're getting Could NOT open editor for ....
@DonJayamanne Python and Jupyter are not dropdown output options when I do that.. it appears as if I don't have the extensions installed but when I check the extensions tab Python is there...
