@guger If the nbconvert command doesn’t work from the command line then it won’t be able to work from vs code either as we are calling the same command to do the convert. Might need to try re-installing jupyter or creating a new environment to see if that works. I’m closing this issue for now, but if the command is working from the command line, but not working from vs code, just ping back and I can reopen and investigate.
