Problems debugging usin the Visual Studio Code command line debugger

I am fairly new to VS Code (IDE) and Python (I have plenty of experience with Visual Studio and C#). I have written the following Hello World type program (test.py) using VS Code:

import sys

def main():
    print(sys.argv)
    print(sys.argv[1])
    print(sys.argv[2])
    print("hello world")

if __name__ == "__main__":
    main()

The Launch.json looks like tis:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python Debugger: Current File",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "args": [parameter1", "parameter2"]
        }
    ]
}

If I select Run/Start Debugging then everything works as expected i.e. the arguments passed are printed to the terminal in VS Code. If I add a breakpoint then the code stops as expected at the breakpoint.

I have come across this webpage and specifically the "Command line debugging section" (https://code.visualstudio.com/docs/python/debugging). I tried this (as stated on the webpage):

1. Open terminal

2. Type: python -m pip install --upgrade debugpy

3. Press enter

4. Amend the launch.json to this:

   {
   "name": "Python Debugger: Attach",
   "type": "debugpy",
   "request": "attach",
   "connect": {
   "host": "localhost",
   "port": 5678
   },
   "args": [parameter1", "parameter2"] }

5. If I Run/Start debugging at this stage then everything still works as expected i.e. the arguments passed are printed to the terminal in VS Code and the code stop as expected at the breakpoint.

6. Type: python -m debugpy --listen 0.0.0.0:5678 ./test.py

The code errors with this:

0.01s - Debugger warning: It seems that frozen modules are being used, which may
0.00s - make the debugger miss breakpoints. Please pass -Xfrozen_modules=off
0.00s - to python to disable frozen modules.
0.00s - Note: Debugging will proceed. Set PYDEVD_DISABLE_FILE_VALIDATION=1 to disable this validation.

IndexError: list index out of range

If I comment out the following lines, then the code runs from the command line, however breakpoints are not honoured:

print(sys.argv)
print(sys.argv[1])
print(sys.argv[2])

My two concerns are:

1. Why can’t I provide command line arguments when command line debugging? It works if you pass the aruements via a terminal command like this: python -m debugpy --listen 0.0.0.0:5678 ./test.py "parameter1","parameter2". It appears the args in the launch.json are ignored.
2. Why aren’t breakpoints honoured when command line debugging?

I have tried adding the -Xfrozen_modules=off to help with the breakpoint issue (as suggested by the terminal message above), however it makes no difference. I have also tried adding the --wait-for-client flag (mentioned in the link I provided) to help with the breakpoint issue, however this also made no difference.

I am using Visual Studio Code 1.86, debugpy 24.077.775 and Python 3.12.3. Windows 10 64 bit.
