Re: game failed to load 135:3ce8528f (what does it means?)
To make sure I understand what you did and what happened.
When you created the new user folder after moving your current "The Sims 4" out of the Electronic Arts folder or renaming it and starting the game, and using the New Game option, did you go all the way through and create the obligatory sim and place them on a lot and get the error at some point in the process? If you did, when did it show up? When you tried to place the new sim? Or were you able to successfully place the new sim on a lot and didn't get the error?
Or did you get the error in your current save when you moved or copied it to the new user folder? Did you move or copy your mods folder when you moved or copied the save folder? The save needs to be tested without mods and CC in the game just to make sure it's not the save itself that has the problem.
Based on what you said in your first post, I'm inclined to think this is a mod issue. But if you created a new user folder and then a new game save and still got the error without mods and CC enabled and nothing but the resource file in the Mods folder, then it might be the game itself and the repair should have cleared it up. Though, sometimes it does take more than one repair attempt. So, you can try another repair or even two to see if that fixes it.
Hope this helps.
