Failed to load file since it's corrupted

Getting this "Failed to load file since it's corrupted." when trying to open a file. All the other videos on this SD card are all right and playable but not this one, which I needed the most. It just won't open at all! I've got the latest version of your Studio as well as the latest firmware. Never had such a problem before. What should I do, Insta360? I really need this file!!
