Bug report
When running a pip.pyz file with the py.exe launcher (itself launched from a Rust program), the command fails with the error:
Unable to create process using 'C:\Users\Gustav\AppData\Local\Programs\Python\Python311\"py C:\Users\Gustav\.local\apps\pip.pyz --version': The system cannot find the file specified.
Unfortunately, I haven't been able to isolate a fully reproducible test case so far. However, I have set $env:PYLAUNCHER_DEBUG=1 and the output of the failing command is

Unable to create process using 'C:\Users\Gustav\AppData\Local\Programs\Python\Python311\"py C:\Users\Gustav\.local\apps\pip.pyz --version': The system cannot find the file specified.
The key issue seems to be
SearchInfo.executable: "py
(note the unbalanced quotes) which appears to be a result of incorrectly parsing the following:
SearchInfo.originalCmdLine: "py.exe" C:\Users\Gustav\.local\apps\pip.pyz --version
I can create the same debug output using the internal _winapi.CreateProcess function:
_winapi.CreateProcess("C:/Windows/py.exe", '"py.exe" -0', None, None, 0, 0, None, None, 0)
So the problem appears to be when the command line passed to CreateProcess contains a double quoted but relative filename.
Your environment
- Python and launcher from 3.11.0b5.
- Operating system and architecture: Windows 11, 64-bit.
