Hacking Homebrew Launcher not booting

[Technicmaster0]

Whenever I try to run the homebrew launcher my wii u (5.5.1) freezes at some point during the initialization, mostly with the "Wii U" logo in the bottom right corner.
I already tried different exploit hosters (loadiine.ovh, wiiubru.com, wj44.ml) and different SD cards (1GB FAT and 128GB FAT32) with different homebrew launcher installations (either the latest from github or the one from wiiubru). I delete the cookies every time and I already tried to delete the save from the browser.
Loadiine works like a charm.
