Np, FYI I've since noticed it goes away after a reboot, then sometimes comes back. Also please note that when the debugger does work, there is no

I have the same issue, please help |

same issue here |

@karthiknadig any thoughts here? Looping you in for Windows expertise since this seems windows specific |
|
Can you share the code that is causing this? |
|
How did you install Python? Is it from the installer or is it the embedded install? That message should only really come up probably if the stdlib code can't be found or somehow the Python install assumes the stdlib is only available as a zip file. |
It was using python.org's official Python 3.12 installer for Windows.
The bug originally happened on some proprietary code that I cannot share, but when trying to narrow down the issue, I found it would even trigger on a basic Hello World example as below. If I set a breakpoint on the first line, the debugger didn't even reach it. if __name__ == "__main__":
print("Hello World") |

Hi @Scrashdown, to clarify this only occurs for 3.12 right? |
|
This might be an issue with that particular install. Can you try uninstall that version of python, and install it clean? There error here is coming for the installation, I suspect something went wrong with that install. |
I've only seen it happen on 3.12, but as it only happens once every few weeks maybe, it's hard to know for sure if changing versions would work around the issue. Anyway I'll switch to python 3.13 and report back if the issue happens again.
Maybe, as stated above I'll uninstall python 3.12 and install 3.13, then report back if the issue happens again. |

Happens on 3.9.13 too, with "justMyCode": false. |
