SD card stopped working on OLED due to corrupted file

I have a switch oled. newest update.

I was uploading save data to the cloud on my switch online apps. when I got to the snes app, it made me update the app first. once it was updated, I couldn't open the app due to a corrupted file. It took me through a menu that gave me the "check for corrupted files" and it didnt find any. So I selected the option to re-download the software. once the app was deleted, my sd card stopped working.

I literally just Played through firered, and caught a shiny hooh after 10 hours of resets.

someone please help!
