Dumpling web launcher freezing before launching

[CroqueMr67]

So, whenever i try to use the web launcher, it freezes my wii u, and just doesn't do anything, it just stays like that forever.
I have an 8 gigs fat32 formatted usb flash drive, so it should work
My wii u isn't modded/ homebrewed/cfw'd in any way
My system is up to date and i reset the browser save data after every try, but it doesn't do anything
I'll put a video of it in the report
