Sims 4 Gallery Won't Load

Step 1. Move The Sims4 folder to the desktop
Step 2. Fix the game in Origin
Origin/ My games library - right-click on TS4 - option "Repair game"
You have to wait until Origin will fix all packs, not only the base game.
Step 3. Turn on the game - a new game folder will be created and you will have two - one old on the desktop and one new
Step 4. Check if you still have this problem in the newly created game folder. Start a new game with random sims and play by 5 minutes.
If the problem disappeared
Step 5. Delete in the new game folder following folders:
"saves" and Tray.
Step 6. Go to "The Sims 4" old folder and copy - your "saves " folder.
Step. 7. Paste this folder in a newly created game folder.
Step 8. Do the same with Tray folder and TrayDeleteItems file if you have this file in the old folder on the desktop
Step 9 Check if there are newly updated version mods you are using. Then copy and paste your mods and CC from the old mods folder to the new one. First copy the scripts mods every time checking if the game is working properly. If you have a lot of CC try 50/50 method ( divide your CC into smaller batches for example 50 pieces in one subfolder and check these subfolders one by one)
Step. 10. Launch the game and check if this problem disappeared in old saves.
The last step - delete The Sims4 folder from the desktop
Your saves and library will be not changed or damaged
