Here's a summary:\n\n**Issue (Django #32177):** `execute_from_command_line()` crashes when `sys.argv[0]` is `None` because the `CommandParser` in `ManagementUtility.execute()` doesn't explicitly set `prog`, causing it to fall back to `sys.argv[0]`.\n\n**Fix:** Added `prog=self.prog_name` to the `CommandParser` constructor in `ManagementUtility.execute()`. This ensures the program name is derived from the `argv` argument passed to `execute_from_command_line()` (via `self.prog_name` which is set in `__init__`), rather than from `sys.argv[0]`.\n\n**Changed file:** `django/core/management/__init__.py` — one line changed to pass `prog=self.prog_name` to `CommandParser()`.",
