The problem came up when I tried to change an item / hex code via Visual Studio, which opened and tried save game. And I have probably done something wrong and since then this Error has been coming. Please, if anyone knows what you can do, please help us. thank you!
Happened to me today. I had Custom cheats via Quick mode on a Slot 9 save. However, I removed the Slot 9 save from my PS4, transferred the another Save Slot (Slot 3) to a USB and tried to edit. I got the error.
What I did was, I went to the Save Wizard Backup folder and removed the Slot 9 Custom Cheats in swusercheats.xml (using notepad) and I was able to get it to work again.
Hope this helps.
