I have a problem in uploading my model

I am working on an object detection project that is supposed to detect one class. I have 10000 images, so I decided to train a custom model on 1000 images and then upload it to help me in annotating the rest of the images, but I am facing a problem where when I am trying to upload the custom-trained model YOLOv12, the RoboFlow interface says that the model uploading failed and I can’t use it. What to do?
