I have been playing the Witcher series from 1 on Steam Deck. All games are from here, GoG.

I imported TW1 save in TW2 and I didn't have any issues.

Now, I want to play TW3 (again) but now importing my save from TW2 but it doesn't work. I copypasted the save in the correct folder because the game detects the save but it says that "it is unavailable". Any way to solve this?
