Do you happen to have GoPro Plus? Is the auto-upload to the cloud set on your app?
If the files are already deleted on the SD card, unfortunately, we do not have any preferred methods of data recovery.
This may vary from SD card manufacturers of the preferred methods for recovering your data.
However, you may be able to perform a Google search to find various data recovery options to recover the footage that had been lost.
It is also best not to record any new photos and or videos with the card that had been used. This will overwrite the files that may have been on there to where it would not be possible to recover.
