Please check the "show dialog", so that we can see what the game tells you when you take the screenshot. Also someone got this fixed after resetting the game, so that might be with a try! 🙂
Try resetting your files to factory settings.
- Make a backup; copy your The Sims 4-folder from C:\Users\Username\Documents\Electronic Arts to an external drive or somewhere else on your computer, for example your desktop.
- Rename the The Sims 4-folder in C:\Users\Username\Documents\Electronic Arts to The Sims 4_backup
- Start the game, make a new save, and see if the error is gone.
(The game will have created a new The Sims 4-folder in your documents, this is supposed to happen)
- If yes, continue
- If no, post a reply telling us the error is still there
- Start putting folders back in the new The Sims 4-folder. Observe! After every file/folder, start the game and make sure it still works, before putting in the next one.
- Options.ini - your game settings
- Saves - your old saves. The sub-folders are not needed. If putting these back causes problem, try putting one back at a time.
Screenshots - don't do this, maybe the folder is full, who knows :P- Custom music - if you have any
- Tray - your library objects; like lots, rooms and sims
- Mods - your mods and cc, might cause problems when putting back
If putting back one of the folders was problematic and you did not work it out, please post a reply and we'll see if we can find what your problem is!
