Exit the game and delete cache files: https://sims4.crinrict.com/en/2014/09/delete-cache-files/
That didn't fix it at all. The library item is still showing as a red cross and I still can't edit the original gallery item.
Have you tried resetting your user folder?
You can reset your user folder by renaming it or moving it to the desktop and playing the game so it makes a new Sims 4 folder. Here's a how-to:
Sims 4 Factory Reset -
Rename your Sims 4 folder to Sims 4_Backup. The game will create a new folder next time you play. - Renaming it or moving it to the desktop will help you have a backup and keep your Sims 4 files safe.
Repair the Sims 4 game. In Origin > Game Library - right-click on Sims 4 and select Repair. - To make sure the install files and such are in working order.
Try launching the game, play a new save. If it's not working, don't save. However, if everything is playing okay then start putting the files back. (list of files and folders below).
- Options.ini (User game settings)
- Tray Folder (Sims/Houses/Commercial lots and rooms)
- Screenshots/Videos/Custom music
- Rest of the save games, if any.
(leave out slot_00000001.save which is the autosave. It is not used anymore.)
- Custom content like clothing, hair, skins, and makeup
- Mods (Put these back one by one to make sure they all still work)
Custom content can become outdated with most new game patches. If the game works when the Mods folder is removed, then one or more of the mods and/or custom content has become outdated and will need to be removed or replaced. EA/Maxis aren't responsible for broken mods/cc. It's up to the creators to fix.
Try the 50/50 method:
1. Move all the mods and cc out into a temporary folder on the desktop.
2. Move a few files back at a time. Load the game to make sure it loads and everything is good.
3. Delete the localthumbcache.package from the Sims 4 folder.
4. Repeat steps 1 - 3 till there is no more files to check.
** While your testing, don't save the game. If you find any problems, delete the mod or custom content file.

If you move or rename the Sims 4 folder, the game will no longer be able to find it. When you go to play the game it will create a new folder.
