Lost video files on SD card/5D Mark IV

I took some videos about 20min each. My wife connected the camera to windows 10 computer using USB cable and moved the vodeo files to the computer. Now there are only 0 bytes files for the long videos on the computer, and I can't find the videos on the camera. File expleorer shows 12GB is used in the SD card, which is exactly the size of the remaining raw files. I used Lexar's recovery software and it found some video files of several KBs on the SD card (Sandisk Extreme Pro 256GB). I'm hesitating to recovre these files as they look kind of weird. What's the best way I can get the videos back?

Obviously, don't do any more recording or erasing on this card till things get sorted out.

 

Is this a full size SD card or a micro SD card used with a card adapter? Do you have a USB SD card reader that you can try instead of downloading from the camera? Has your Win10 machine got all the latest updates? Have you tried downloading on a computer with an earlier operating system?

 

I've had some luck recovering files with the free version of Recuva, but I was only looking for still images, not video files.
