Invalid Python interpreter when using "maturin develop"

[Skelectric]

Discussed in #1121

Full error:
(venv) F:\Projects\Python Projects\punge\rust>maturin develop
🔗 Found pyo3 bindings
💥 maturin failed
Caused by: The given list of python interpreters is invalid
Caused by: Python interpreter F:\Files at random\theoretical python\punge\venv\python.exe doesn't exist

• The path that it is trying to point to is where I used to have my python project.
• As outlined on the readme, I have set "PYO3_PYTHON" and "PYTHON_SYS_EXECUTEABLE" (system and user environmental variable) to a valid python intrepreter
• The path that maturin wants to use is not listed when viewing the environment variables from windows:
  
  -But does show up in python when using "os.environ["PATH"]".
  
• Running dir env:Path in PowerShell does not show the invalid Python interpreter path for the 'Path' variable
• This is what my User and Machine variables look like:
  
  
• The "C:\Users\Spencer\AppData\Local\Programs\Python\Python310\python.exe" or "F:\Projects\Python Projects\punge\venv\Scripts" path are both valid paths.

Any help would be appreciated

Maybe tangentially related:

#957 (comment)

The maturin list-python --target command does not want to work with any of the params I pass it (on Windows).
Perhaps if it worked, it could be used as a workaround for this issue?

I see this is a duplicate. Closing...
