a somewhat reliable fletchling fix:
first go to this link
https://gofile.io/d/Sink9L and download the ryubing in there, it already has known working firmware and prod keys, thus being able to see and open the game
then download the config file and move it inside the portable folder, that way it shouldn't crash during the fletchling cutscene
schizo theory: spamming F5 during said cutscene might help
and if it still does, download the save, extract it, rightclick the game, open the user data folder and move it there
