Homebrew Wii U Homebrew Launch error: "FSGetMountSource Failed." (Wii U Browser Exploit)

[GoldenTreesYT]

Hi, I'm trying to hack my Wii u so I can load my game backups. I am following the guide on wiiu.hacks.guide but every time I do the part to load the launcher, without even trying to load homebrew, my console just brings up a black screen on both the TV and the gamepad that says FSGetMountSource Failed in white text on the top left corner. I also tried following a video before this, getting the same error every time...

My Wii U Firmware is 5.5.2 by the way, and I'm using the black 32 GB console.

Ensure the SD card in the Wii U FAT32 formatted.

When the SD card is in a card reader on Windows you can right click, go to properties and it should tell you the file system the card is formatted in.
