I was in Novigrad doing the 'Get Junior" quest which led into the "Count Reuven's Treasure" quest on PS4. The game began to crash once every hour or so. I was able to to reload one of my saves and push forward until the game crashed again and made all my save games unloadable. Now after reading about the troubleshooting that others have done with limited to no success, I guess all I can do is wait for a fix. But if my saves are useless now I will not start this game over. I have put way to much time in. Seems like a lot of you feel the same way.
