@simsluvr90Try to do a factory reset in this way.
Step 1. Rename The Sims4 folder to "The Sims4 old"
Step 2. Fix the game in Origin
Origin/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, one new
Step 4. Start a new game this random sim and play 3 minutes.
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
Step 9. Check if there are newly updated version mods you are using.
Then copy and paste your mods and CC from 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. If all is OK - delete The Sims4 old folder.
Your saves and library will be fine and nothing will be damaged
If your old save still will not work after this - it can be probably bugged.
Always save the game with the "save as .." option with the next number. Keep only the last two saves. To delete older ones - click X in the upper right corner on the image of the "save" After each patch you need to delete localthumbcache.package file and all folders what have word "cache" in the name
