I'm on SX OS 2.9.3 and Switch FW 9.0.1. After formatting to FAT32 my microSD and installing some games, I was able to play all of them. Then I was trying to install The Witcher 3 Mod (as described here in the official topic of the release) and it worked well. Then after a few hours I was unable to play any game on the Switch. Every time I try to launch a game, the screen becomes black and I have to reboot my Switch holding the Power button. How can I solve this problem? Reinstalling the games doesn't work, same error: black screen.
