hal_delay() not working

So I've created a project and am trying to use the HAL_delay(10); but it gets stuck at this function when im trying to debug.

I have been changing the clock and enabling the TIM2 so I don't know if i've messed something up. Here are the settings that I have:

And that is about it

This is my main function code. I have also found out that if I comment out SPI communication then I2C works but if I uncomment it and use SPI and I2C then in the I2C part of code it gets stuck after like 3rd transmit function

in main, see if you can get past HAL_Init() or does it go to Error_Handler()?

int main(void)
{
  /* USER CODE BEGIN 1 */
	uint8_t buf[256];
  /* USER CODE END 1 */
 
  /* MCU Configuration--------------------------------------------------------*/
 
  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
	if(HAL_Init() != HAL_OK)
	{
		Error_Handler();
	}

how about removing all your peripherals you've added, SPI, I2C, TIM2. See if your RB11 or RA15 toggles 

  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {
	  HAL_Delay(1000);
	  HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_15);
    /* USER CODE END WHILE */
 
    /* USER CODE BEGIN 3 */
  }
  /* USER CODE END 3 */

no idea actually, seems normal to me in the editor. I changed theme to black now to see the difference but they all look the same either way
