slow copy crash and photos gone on SC2 (recovery?)

Hello everyone,
I was transferring the images from my SC2 to my phone, transfer was very slow. Next thing the app had crash, and all the photos are gone, not on the phone or camera (copy setting was on). Any advice of how to recover the images? the SC2 does not have an SD card that I can remove to use software for recovery and “Recuva” and “Ease Data Recovery” dont recognize the camera. Thanks
