Nintendo Switch error code 2016 0641?

I got the error message 2016 0641 (microSD card is not recognized) since tonight. I have used the switch with a microSDxc since day 1 release and had no problems. Until today. Switching off, taking out and reinserting did not help. I don't have another microSD card. Formatting the one I have used so far is also not possible because it is not recognized.

So shortly before the release of Animal Crossing it's a little frustrating. Sending in for repair would cost me money as well as time… Does anyone know how much?

Would be really happy if someone knows what else I could try.

The SD cards don't last forever. I think the switch has nothing. Buy a new SD card.

Was actually like that, new SD card in and everything was fine.
