Hello, everyone. Thank you for taking the time to discuss this issue during your busy schedule. When I first encountered this problem in the afternoon, I improved my code and put the CropController into the constructor to ensure that the initialization is completed when the object is instantiated. In fact, he worked. But when I ran it again at night, this error occurred again. I am not sure if this is a bug, and I hope to get everyone's help. Below is the error message and some codes. Thank you
