Photos disappeared from Memory card

[bubusam13]

Hello, I used my Nikon D5200 to take some shots yesterday at around 3 PM. The photos turned out well, and I immediately showed my family members.
There will be about 20 of those. When I attempted to copy them to Lightroom later that evening, I was surprised to discover that those images were missing.
The memory card contained all of the older images, but none of the ones I took yesterday. There are no hidden files. I also used a card reader I used to verify the SD card.

Can anyone shed any insight on the potential cause?

Did you try running some recovery software on the SD card? It probably got deleted accidentally.

No I didnt delete it accidentally. I tried again. I clicked a few photos, I was able to see them in the camera display. But when I tried lightroom and even file explorer, photos were not there.
Now it says the memory card is corrupted.

Oh sad then. I guess only thing left is to try different SD card.
