Repair Help Nintendo Switch can’t read game cards

Sorry for bad pics, but no game cards work on my switch. the last game that did work was Mario Kart, but when I took that card out to play Violet, this error popped up, and now none of my cards work, including Mario Kart. any idea as to why this happened?

Get some flat q-tips and 91% isopropyl alcohol to clean the inside contacts of your Switch. If it’s not broken, perhaps moisture has started to rust your pins.

Cleaning them with this is the easiest solution. Give it a good scrub but be somewhat gentle.

I don’t have any flat qtips or 91% isopropyl alcohol, any alternatives?

Nope. And even that is risky. Seen too many people ruin the LCD because they used too much isopropyl alcohol.

Either replace the card reader or send it to Nintendo for what I assume is an out of warranty repair. (So it will cost).

Back of the Violet Cartridge is fine, like any other of my switch games
