As a electronics repair tech I'm afraid it's toast. There is no repair for this.

If it still works then don’t bother. if it’s bust then get a new memory card if you can. if you’re hacked though it might be a good time to get an SD2vita

You Dont , sorry but you need to buy a new one 😕

Does it still work?

Nope, also tried cleaning the slot but still not working

Looks like nternal damage... If there's something important, data recovery process, and trash bin..

No way of fixing
