Can not free gpu memory

[TuyenNL2002]

Hi, I have a problem when freeing memory: using cuda_preprocess_destroy() does not free everything, in addition, if I declare and use 02 objects "YOLOv11 yolo1, yolo2;" on the same app, when calling cuda_preprocess_destroy() for yolo2, it makes yolo1 have an error "System.AccessViolationException: Attempted to read or write protected memory".
