Having the sysmodule enabled prevented games from recognizing my plugged in gamecube's inputs (though outside of games it worked as normal). Disabling it made it work again.
How to reproduce:
-Enable sysmodule
-Plug in usb controller (I used a GameCube controller with usb-c adapter) to Switch's charge port
-Launch a game
