Micro SD card is no longer recognized by all devices?

My Micro SD card is no longer recognized. She was in the smartphone all the time and suddenly she could not read anymore. All other phones and the laptop can no longer read you. I cleaned the contacts with spirit as recommended. I wanted to retrieve the data via Recuva but that's not because he does not even show the disk. I have nowhere found any more, maybe you still have a tip.

Well, then you'll have to write that down, or not. If that is no longer displayed, no software can read something down there.
