Python subprocess.run() returns error code 3221226505

Context

Implemented test.py with the following code:

from pathlib import Path
import subprocess

def run_test():
    """
    """
    some_exe = Path('path/to/some/exe/file.exe')
    arg1 = 'some_arg'
    some_tag = 'something_something'
    arg2 = f'some_more_arg_{some_tag}_"someString"'

    some_cmd = [ str(some_exe), arg1, arg2 ]
    print(" ".join(some_cmd))
    results = subprocess.run(some_cmd)
    if(0 != results.returncode):
        print(f"error code: {results.returncode:d}")

if "__main__" == __name__:
    run_test()

When running the code with python (python test.py), subprocess.run() returns a Windows error code 3221226505. However, running the commands printed by print(" ".join(some_cmd)) succeeded without error.

Problem

How to run the command with Python without error?

Solution

Remove the double quote (") in arg2:

arg2 = f'some_more_arg_{some_tag}_someString'

Note

It's still unclear to me what's going on here, but it looks like the problem of the executable not able to properly handle the double quotes in the arguments.
