I don't have a Nintendo Switch

Sorry, how can I do it? I'm playing on my android tablet.

Hello, I started Pokémon Sword on Yuzu and after receiving my starter (Scorbunny), I wanted to edit it giving it the adamant nature, ability libero, perfect ivs and maxed evs, after that I export the save file, overwrite the one that I opened, in the same folder (I already made a backup) and then try to play. But when I start the game, it shows just an infinite loading but it doesn't start. There's no corrupted messages or anything else. If I delete the save file or put back the old one, it starts with no problem. What can I do to make it work? Thanks in advance.
