Use external hdd or ssd instead. Or if you want to use the sd card then go here: https://gbatemp.net/threads/sdusb-the-modern-way-to-play-wii-u-games-from-sd-at-full-speed.655744/
Either use FTPiiu to manually delete the files from the usb or reformat the stick and redownload the game. It's a fool's errand anyway because you'll probably run into the same issue.
@salazarcosplay, if you ask how am I, well... aside from the fact that i cant stop thinking about killing myself i guess im fine, and my throat got better
If you decide to take the easy way out, at least do it some interesting way, like 5 fishing magnets and ropes... Run out to the space x rocket as it's about to take off.... Ohhhh add some snow skiis and skii into to space!!!
