Hi @jmwielandt 👋 Thank you for reaching out.

Sadly I couldn't reproduce your issue:

📋 Here's why all these variables are being displayed: When you run "Start Debugging" or "Start Without Debugging" all those ${env:*} debugging session variables are set behind the scenes by VS Code and/or the extension.
When you start debugging again in the same integrated terminal, a debugging session will be re-created ➡️ these variables will be inherited ➡️ the command being run is suddenly very, very long.

There is an experimental VS Code setting to start integrated terminal sessions with a clean environment, sadly it doesn't work on Windows otherwise I would've asked you to try it.

👉 There isn't anything we can do in the extension at the moment to fix this, so I will be closing this issue once you let me know if any of these workarounds work:

• close the Python debug console every time you are done debugging (so that it re-creates a terminal next time)
• use a different shell (git bash, cmd, another version of powershell-core or Windows Powershell)

Thanks!

[jmwielandt]

Thanks for your answer, @kimadeline !

In fact, closing the Python debug console works, thanks!

Greetings~

PS: closing the python debug console fixed the problem for ever, i can't understand this ;-;

[ChaosGT]

I've got the same problem! I've prompt the bug under vscode.
microsoft/vscode#81023

[ChaosGT]

It is very easy to reproduce the bug:

1. Open a single python file
2. Choose Debug -> Start without debugging
   3. Repeat step 2 for several times
   The running command may occasionally include all the system environments, cause the shell get System.ArgumentOutOfRangeException.

Hi @ChaosGT 👋 thank you for reaching out. Please try one of the workarounds I mentioned above.

In the issue you opened in the VS Code repo you also wrote that sometimes VS Code will become unresponsive, if it happens again please open a separate issue for that.

Thanks!
