PermissionError: [WinError 5] Отказано в доступе

Я новичок в Python. Я использую многопроцессорную обработку для пакетной программы, такой как xcopy, с хост-компьютера на удаленные ПК. Я получил ошибку разрешения, такую ​​как *DUPLICATE_SAME_ACCESS*. любая помощь будет очень полезна.

Оболочка IDE. :

• Кеплер
• Python-3.x
