Thank you for your reply.
Yes, I do. The thing is that I can exactly find the save from my PS4 on my loading screen of my Steam game.
And I ocassionally opened that save once but unforunately I didn't save it locally on my Steam, then I tried hunderds of times to reopen and didn't succeed once again.
So what should I do? I have my PS4 version of this game in 2015 and the save was finished in 2016 after finishing Heart of Stone and Blood and Wine. I really want a New Game Puls on my steam continuing my old save.
Thanks again for your help.
