F_open looping

[Chris5]

Using Nucleo-H753ZI
Trying to write to SD card using:

  FATFS FatFs;
  FIL file;
  FRESULT FR_Status;
  FATFS *FS_Ptr;
  FR_Status = f_mount(&FatFs, SDPath, 1);
  if (FR_Status != FR_OK)
  {
	  printf("Error! While Mounting SD Card, Error Code: (%i)\r\n", FR_Status);
  }
  else{
	  printf("SD Card Mounted Successfully! \r\n\n");
  }
  static char hello_world[] ="hello world";
  UINT bytesWritten;
  if(HAL_SD_GetCardState(&hsd1) != HAL_SD_CARD_TRANSFER) {
      printf("Card not ready\n");
  }
  FR_Status = f_open(&file, "hello_world.txt", FA_WRITE | FA_CREATE_ALWAYS); //tried 0:/ and / infront of hello_world.txt
  FR_Status = f_write(&file, hello_world, sizeof(hello_world), &bytesWritten);
  FR_Status = f_close(&file);

The SDMMC peripheral is initialized in 4 bit mode and using a 20MHz clock.

Error occurs in stm32h7xx_hal_sd.c at:

It goes through the first sets of the for loops find then start going between the first if statement and the second.
