I have the same issue since upgrading from 1.85 to 1.86. From my little investigation I suspect that this is due to the changes from I see that the application being spawned begins with: It looks like the Current Directory parameter (following -d) is not set, probably an empty string from what I can see see looking at the code :
I pretty agree with the response above that some troubles are in external terminal service function .
Update, if it's helpful, the launch that we're using is of type:
This comment is correct. Based on the DAP for RunInTerminalRequest, even if was null, it would use as the directory before. That commit breaks the scenario where a debug adapter sends an empty string for 'cwd'. See
any update on this?

Please fix - downgraded to 1.85 to deal with it; auto-update just brought 1.86 back and it's broken again... This is a major usability issue
Thanks for the investigation, Sebastian. I applied a fix to ensure a directory is passed when launching Please let me know if that resolves the issue. is still respected as the shell we launch use in the windows terminal, but since the last release we prefer to run that in the Windows Terminal since there were issues that came up if we launch directly.
So I'm getting this ! with the following config: and additionally the default value or manually setting: both open WT, though they do have cmd running inside. Which it sounds like is the expected behavior.
Closing this issue now that the candidate PR has been merged.

I'm still seeing Tyler's issue with the latest Insiders. Let me know if there are any logs I can attach.
I am still seeing this issue. It is likely a problem with core VS Code, not the cpptools extension. See my comment here: TL;DR: Set to be (or ) to work around the issue.
