Not sure if this will help, but iIf you're using the Flatpak version of Bottles, make sure you have the folder the file you're trying to play is in allowed to the program. You can do this via CLI, or with Flatseal.
If that's not it, I got no idea, but wish you the best.
you need to find the proton save file folder and that should work thats how ive been doing it just go into your steam compat data folder and if you are using dolphin search for VoTV
