python path not being read at run time in muti-root workspace

[dss010101]

Type: Bug

Behaviour

Expect python path to be set based on one of the settings below at runtime

I also posted a question on stackoverflow to see if perhaps im just not doing this correctly: https://stackoverflow.com/questions/74758616/vscode-multi-root-workspace-specifying-python-path-in-env-files

Steps to reproduce:

1. basically i would like to conditionally load the python paths based on different .env files driven my the OS im running under, either windows or linux (via WSL). The problem is i cant even get a multi-root workspace to load these paths regardless if i put them in my env file or if put them in my settings.json

This is what the folder structure in vscode looks like:

here are the relevant files' content in my current state - at this point im just adding python paths everywhere given im not sure exactly which of these settings are needed - and the documentation isnt clear with regards to multi-root workspaces how these various means of setting python paths should be ideally set. I'm also just trying to get this to run on windows for now:

project1:launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Run App",
            "type": "python",
            "request": "launch",
            "program": "${workspaceFolder:project1}/src/app/app.py",
            "console": "integratedTerminal",
            "justMyCode": true,
            "windows": {
                "envFile": "${workspaceFolder:project1}/.env"
            },
            "linux": {
                "envFile": "${workspaceFolder:project1}/.env_linux"
            }               
        }
    ]
}

project1: settings.json:

    "terminal.integrated.env.windows": {
        "python.envFile": "${workspaceFolder:project1}/.env",
        "python.pythonPath":"${workspaceFolder:project1}/src:${workspaceFolder:project1}/src/app:${workspaceFolder:project1}/utils",
        "PYTHONPATH":"${workspaceFolder:project1}/src:${workspaceFolder:project1}/src/app:${workspaceFolder:project1}/utils",
    },
    "terminal.integrated.env.linux": {
        "python.envFile": "${workspaceFolder:project1}/.env_linux",
    },
    "python.envFile": "${workspaceFolder:project1}/.env",

.env file
PYTHONPATH=./src:./src/app:./src/utils:./project1/src:./project1/src/utils:./src/app:./src/services

project1:app.py
from utils import utils

So i know it's reading the launch.json located in project1/.vscode, as the debug configuration shows up and i can run->debug.
The problem is when it run the app.py file, at the import above, i see the error:
No module named 'utils'

so that tells me it's not finding the python paths either in the .env file or the settings.json file.

1. What it the proper way to loading python path for specific projects in multi-root workspace project
2. Can this be done using .env file instead of a settings.json given that at run time, i would be using the .env file and avoids having to maintain python paths for the project in multiple places
3. Can we selective load different python paths in vscode depending on wether im running vscode on windows or whether in running on linux (via WSL)
