This may seem like splitting hairs if your data gets corrupted, but the good news is that all is not lost - literally. “It’s more of an operating system failure than a game failure,” SciresM said. So, if you encounter the problem and happen to be using FAT32 or the Switch’s internal memory, all you have to do is restart the game. Those using the exFAT format are, in general, prone to sometimes having data corruption issues on the Nintendo Switch, which is why people often tell each other to format their cards as FAT32. Formatting builds that structure, and there are a few ways to format cards. In layman’s terms, SD cards need to be structured before they can hold data. “When it happens, IF you use exFAT you get corrupted.” What we do know is that how your SD card is formatted can affect what happens next. We don’t yet know what is causing the failure, only that, once it happens, Sword and Shield crash. “Basically, the operating system tries to retrieve data from disk, and that fails,” SciresM told Polygon. (If you’re hearing about it everywhere, it’s probably because it sounds terrifying, so people want to warn each other.) But, if you do come across the bug, what is actually happening? The first thing you should know is that the glitch isn’t widespread, so the chances of you encountering this bug are somewhat slim. However, based on the expertise of Pokémon hackers like it seems that the panic has gotten some details about the issue wrong, at least initially. Polygon reached out to Nintendo for comment, but the company did not respond in time for press. OEFHZErLCx- DeathChaos November 15, 2019

Now everything on my Switch looks like this, even the cart games are asking for a redownload.

Game crashed on an attempted autosave (or at least I assume so), I then the game crashed on boot to I put in my smash cart to test, smash crashed on boot too, so I rebooted my Switch.
