Nintendo Switch SD Cards Game?

I hope someone can help me. I got a micro SD card for the switch because I downloaded the most games in the shop and the storage space was tight. I also downloaded a few extra games so that they are now on the memory card. Unfortunately, the games do not start anymore. If I want to play a game of the memory card always appears "The software can't be started" when I then search the software for errors is there that the software has no errors. Now I can't play games that I have downloaded on the SD card? Or does anyone help me?

Where did you buy the sd card?

And please do not tell Wish.

Fake micro-sd cards say they have more memory than they really have.

When you download a game, all other data is overwritten when there's no more space left. Or in short = deleted.

You obviously have a fake or a broken card.

Ne I've got the card here in my electronics load and on the switch itself is also displayed 128 GB

For fake microsd cards also 512 gb are displayed. Even if no 512 gb are available.

But that your sd card does not work is weird. Go in the settings on "console", then on "formatting options and then on" format microSD card. "Maybe it goes dan.
