stm32g491cet6 ADC interruption and Hal_Delay not working - ide

Question

I have a number of issues with stm32g491cet6.
When using the ADC interrupt, it remains in an infinite loop. When using the HAL_Delay () function, an infinite loop also results.
The code is simple and runs on the application board with stm32f103 but not on stm32g491cet6 (two separate projects of course).
The PWM work good.
Any ideas?
int main(void)
{
/* USER CODE BEGIN 1 */
/* USER CODE END 1 */
/* MCU Configuration--------------------------------------------------------*/
/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();
/* USER CODE BEGIN Init */
/* USER CODE END Init */
/* Configure the system clock */
SystemClock_Config();
/* USER CODE BEGIN SysInit */
/* USER CODE END SysInit */
/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_ADC1_Init();
MX_TIM1_Init();
/* USER CODE BEGIN 2 */
HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_1);
if (HAL_ADCEx_Calibration_Start(&hadc1, ADC_SINGLE_ENDED) != HAL_OK)
{
/* Configuration Error */
Error_Handler();
}
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
HAL_ADC_Start_IT (&hadc1);
HAL_Delay(100);
}
/* USER CODE END 3 */
}
void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc){
HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_4);
}
