Help! When I deploy a neural network model to a development board the model fails to initialize!

I have version 6.7.0 of STM32CUBEMX, version 8.1.0 of X-CUBE-AI, and my stm32 development board model stm32h743iit6. using the Analyze button on STM32CUBEMX works. But when I generate c code for my onnx model and deploy it to the development board, my model fails to initialize. When I traced how the problem happened, I saw the ai_platform_network_create function. It's a black box function and I can't get inside it (it seems to be an officially provided function). I can compile and burn normally using the Keil software, but I can't proceed further when I run into this function. When I use debugging and click on the Stop button while stuck, my Call stack+Locals window prompts an HardFault_handler error. How do I get my model to run properly?
