If the flight was saved to your phone or tablet you can email the flight data to yourself through the FreeFlight6 app in .json format. But since it crashed I’m not sure this approach will work since the flight may not have been downloaded to your device. Worth a shot though. I’m sure it’s stored someplace in the bird as well but that’s beyond my know how. You’re lucky you got it back even if was a year later! Good luck
As far as I am aware nobody, besides Parrot, is able to decipher the.bin files on the SD card. If you have another Anafi you could try I sorting the SD card into that and powering it up to see whether the .json files are transferred.
