Hi, thanks for taking the time to report this.

Can you open a terminal when you open a non-Python workspace? That is, open a new folder someplace where no Python files exist (create a new workspace with no files) and then open a terminal window.

Please could you copy your current settings.json? Both for the user as well as for the current workspace?

Do you have any profile settings set up for your Powershell environment? Open a terminal window then type:
> gc $Profile

The python terminal still does not activate when I have a python-naive workspace.

Not 100% certain here, but if your python.pythonPath: points to pythonw.exe I think that may be the problem.

Could you please set this in the workspace setting and report back?

{
    "python.pythonPath": "C:\\ProgramData\\Miniconda3\\python.exe"
} 

Thanks.

Alas, same issue.

Something I should mention though is that the debugging terminal hasn't had issues using either pythonw.exe or python.exe. Additionally, the shell seems remarkably slow. Even printing

and the next input line takes several seconds.

[mattmj]

Update: I tried using cmd.exe as my default terminal and it actually worked as expected. Perhaps I was wrong in assuming this was a python issue instead of a powershell issue.

Thanks for your help.
