STM32L4 not exiting sleep mode

[JDarg]

When trying to implement sleep mode it appears the code enters and exits sleep mode once and then gets stuck in sleep mode after and will not wake back up. I posted some code below of what I believe affects the sleep function. I want the code to sleep, wake up due to interrupt and perform function, and then go back to sleep until next interrupt. Using STM32L476VG and True Studio

void init_All(void){
	MICRO_SPI_Init();
	init_wireless();
       FLASH_INIT();
       power_init();
       enter_sleep();
}

int main(void)
{
  HAL_Init();
 
 
  /* Configure the system clock */
 
  SystemClock_Config();
 
 
  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_SPI3_Init();
  MX_SPI2_Init();
  MX_UART4_Init();
  MX_USART1_UART_Init();
 
  __HAL_UART_ENABLE_IT(&huart4, UART_IT_RXNE);		//Enables Receive Interrupt
	init_All();
	done=1;
    while(1){
     }
 
}

  GPIO_InitStruct.Pin = MICRO_CS;
  GPIO_InitStruct.Mode = GPIO_MODE_IT_FALLING;
  GPIO_InitStruct.Pull = GPIO_NOPULL;
  HAL_GPIO_Init(MICRO_CS_PORT, &GPIO_InitStruct);
 
  /* EXTI interrupt init ERB Clock Select EXTI12*/
  HAL_NVIC_SetPriority(EXTI2_IRQn, 1, 0);
  HAL_NVIC_EnableIRQ(EXTI2_IRQn);
}

{
 
	if (GPIO_Pin==MICRO_CS)

		sendDataState();
	}
 
	 enter_sleep();
	}
 
}
