Research direction

No CPython source file, test, or entry point is identified. Start by reproducing the subprocess.Popen() and os.system() examples on Windows 10 with Python 3.11.0, then compare them with manually launching C:\BackUp\Backup.exe. Done requires a confirmed, reproducible CPython problem with a defined expected behavior.

OS-windows topic-subprocess type-bug

Bug report

The following two lines of code execute the software, but the software fails midway due to a missing DLL: "Failed to execute 'regsvr32 /s CommonEvent.dll'".

subprocess.Popen('C:\\BackUp\Backup.exe', shell=True)

os.system('C:\\BackUp\Backup.exe')

擷取
When manually executing C:\BackUp\Backup.exe, the program runs and completes its task without issue. I have looked for a solution but have not been able to find the cause of the problem. I would appreciate any help.
