[A clear and concise description of the bug]

Steps to Reproduce

1. Create a Python project in VS
2. Download and install Python runtime from VS installer
3. Run the Python project

The following error occurs:

Error processing line 2 of C:\Users\stellahuang\AppData\Local\Programs\Python\Python39\etwtrace.pth:

This is because sys.orig_argv is a built-in attribute that's only available in Python >= 3.10.

@AdamYoblick The .pth file is a mechanism to execute initialization code during Python startup. Do you know why etwtrace.pth is present in C:\Users\stellahuang\AppData\Local\Programs\Python\Python39? I was expecting it to only be at %LocalAppData%\Microsoft\VisualStudio\<Version>\Extensions\Microsoft Corporation\Python - Profiling\<Version>\etwtrace

[AdamYoblick]

Hmm I'm not sure. Have you pip installed the retrace package into your local 3.9 environment? Otherwise I don't know, maybe Steve would know better :)

I can't repro anymore, maybe I just accidentally copied it over during testing.
