I was kinda dumb and haven´t seen that my 3DS was still powered on so I have taken the SD card out while it was in TWLoader and in sleep mode, wanted to replace some files, after switching the 3DS off and reinserting the SD Card, Launching TWloader did end with a crash back to the homemenu and a reboot reinstalling did not remove this issue, also Pokémon Sun got srewed, the banner is gone and launching ends up with an "Sd card was removed, press HOME..." error, also the eshop "repair" fails at 99% I have no clue whats up, but I guess some stuff on my sd card got corrupted
