can't debug anything

As soon as I start the debugger vs code shuts it down. Reinstalled the python extensions, reinstalled vscode 3 times, restarted computer, reinstalled python 3.13, 3.14 and 3.9, tried different launch.json files - Nothing works. I can't debug anything with vscode, but I can with cmd.

Something is absolutely off. launch.json was:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python-Debugger: Aktuelle Datei",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal"
        }
    ]
}

And it only works now as:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python-Debugger: Aktuelle Datei",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal"
        }
    ]
}

I would like to upvote this issue... I down graded the python debugger extension to 2025.10.0 from 2025.14.0. With the revert to the older extension all debugging worked again.

I just hit this issue as well. Downgrading the python debugger extension to 2025.10.0 fixed this for me as weill.

Oh well, yes - Extension downgraded to 2025.10.0 fixes this. No need to work with the old python debug type in the launch.json. The most recent update (today) from the debugger extension is broken.

Hello everyone! Sorry you are facing this problem and I am looking into right now. I was unable to reproduce the issue you are seeing myself so wanted to ask some follow up questions:

To confirm, the behavior everyone is seeing is that once they start debugging VS Code crashes? And debugging through a launch.json config?
Does it crash if you try and "run and debug file" the button in the top right when you open a python file?
What are the versions of your VS Code, python extension, and python environments extension?
What type of machine are you on?

When it fails I was getting an Error dialog saying 'Debug Stopped' when I pressed F5 to debug.

I switched from my desktop where it was failing to my laptop and it ran Ok there. The only obvious differences was the Python version, as listed below.

Desktop

1.105.0 2025.10.0 C:\Program Files\Python311\python.EXE Works
1.105.0 2025.14.0 C:\Program Files\Python311\python.EXE Fails

Laptop

1.105.0 2025.14.0 C:\Program Files\Python313\python.EXE Works

closing in favor of #826 as they seem to be the same. Putting out a fix right now and will let you know when it is out so you can confirm your flow works again. Thanks

meant to close as duplicate of #826, sorry

I'll reproduce in estimated 2 to 3 hours. Just tell us when you deployed sth or if u need some more answers :)

Hello! I have put out a release with the fix. It was release 5 minutes ago (so 11:39 PDT) and has the version 2025.15.2025101002 but this specific version number may different across machine types. Please give this a try and let me know if it works. Thanks!

I just got that new version and it fixes the problem I had. I can now debug again. Thanks.

I maybe jumped the gun a little on that. I can now debug my Python script but now errors get thrown on exit, as shown below

Can you confirm it works correctly through the terminal (not with vscode)? Seems like sys.argv is getting mutated but I am not sure how that would connect to the path issue. You could also try running "clear cache and reload" as this may help reset your environment after the previous bug

Eleanor Boyd (@eleanorjboyd) Did you revoke the .15 version or am I blind? ^^;

I still see 2025.15.2025101002 listed- is it showing any version released within the past 3 hours? I also see it listed on the marketplace site online: https://marketplace.visualstudio.com/items?itemName=ms-python.debugpy&ssr=false#version-history

VSCode didn't want to install it - But I was convincing. Got the version 2025.15.2025101002 running and kept my launch.json with debugpy -> Works like a charm.

Great! I will release fix as 2025.14.1 shortly which should help as well
