CUBEMX Settings as above:
The callback function is as follows：

void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim)
 
{
 
	if(htim->Instance == TIM2)
 
	{
 
		LL_GPIO_TogglePin(CLK_GPIO_Port,CLK_Pin); 
 
	}
 
}

The call code is as follows:

USB_printf("1");
 
HAL_TIM_Base_Start_IT(&htim2);
 
USB_printf("2");

The result is shown below:

After receiving 1, the serial assistant no longer receives it and has no reaction when stuck, the pin turns over normally, and the callback function executes normally.
