os.execvp on windows doesn't wait for the executed program to finish and doesn't report it's exit code

Bug report

os.execvp on windows doesn't wait for the executed program to finish and doesn't report it's exit code. Code:

import os
import sys

if len(sys.argv) > 1 and sys.argv[1] == "my_argument":
    sys.stderr.write("my_argument detected. Exiting with code 1.\n")
    sys.exit(1)
else:
    sys.stderr.write("no argument detected. Calling os.execvp\n")
    os.execvp(sys.executable, [sys.executable] + sys.argv + ["my_argument"])

bat file:

@echo off
python exec.py
if %errorlevel% NEQ 0 (
    echo The script gave exit code %errorlevel%
) else (
    echo Error: The script exited with exit code 0
)

Output from command prompt:

C:\pythonizer\play>exec.bat
no argument detected. Calling os.execvp
Error: The script exited with exit code 0

C:\pythonizer\play>my_argument detected. Exiting with code 1.

Note the command prompt prompted me for a new command before the exec'd process wrote out it's message.

Your environment

• CPython versions tested on: 3.10.6
• Operating system and architecture: Windows 10

Comienza reproduciendo el comportamiento de Windows 10 con el script de Python y el archivo por lotes proporcionados, y después sigue el punto de entrada os.execvp y su implementación para Windows. Se considera terminado cuando el programa ejecutado finaliza antes de que el archivo por lotes continúe y su código de salida distinto de cero se comunica al llamador.
