How to Fix Infinite Loading Screens in Sims 4: first find out whether the problem affects every household or only one save. Back up Saves, Tray and Mods, remove Mods from the active Sims 4 folder, delete localthumbcache.package and test in a new game. If new households load but one older save does not, focus on that save instead of reinstalling the entire game.
Keep your original save untouched throughout testing. EA warns that saving while custom content is disabled can remove missing items from your household, so use a disposable save or quit without saving. A loading screen that hangs before the main menu needs a different investigation from one that appears only after choosing a particular household.
The latest patch introduced several significant system changes involving:
- Create-A-Sim base layers
- interface systems
- gameplay fixes
- save backup functionality
- event integration
Because of those changes, outdated mods and broken custom content are currently causing major loading problems for many players.
Here is exactly how to fix infinite loading screens in Sims 4 after the latest update, including the most common causes, troubleshooting steps, and what players should avoid doing before opening important saves.
How to Fix Infinite Loading Screens in Sims 4 after updates
How to fix infinite loading screens in Sims 4 after the latest update starts with understanding what usually causes them.
In most cases, infinite loading screens happen because:
- outdated mods conflict with new game files
- script mods fail during loading
- broken UI systems freeze interactions
- corrupted cache files interfere with gameplay
- custom content conflicts with CAS updates
The latest Sims 4 update changed several systems that many popular mods rely on, which is why loading screen problems exploded immediately after the patch released.
Remove Mods and Test Sims 4 Cleanly
The first step for how to fix infinite loading screens in Sims 4 after the latest update is testing the game without mods.
To do this:
- Open Documents
- Go to Electronic Arts
- Open The Sims 4
- Move the Mods folder to your desktop
Then:
- launch Sims 4
- load a test household
- see if loading screens still freeze
If the game suddenly works normally, then outdated mods or broken CC are causing the problem.
Honestly, this fixes most infinite loading screen issues after Sims 4 patches.
How to Fix Infinite Loading Screens in Sims 4 – Delete localthumbcache.package Immediately
One of the most important fixes for how to fix infinite loading screens in Sims 4 after the latest update is deleting:
- localthumbcache.package
This file stores cached mod and UI data that often becomes outdated after major patches.
Leaving it behind can cause:
- endless loading screens
- broken interactions
- UI glitches
- save instability
Long-time Sims players honestly delete this file after basically every update now.
Update All Script Mods
Script mods are currently one of the biggest causes of infinite loading screens after the latest update.
Mods currently reported as problematic include:
- MCCC
- UI Cheats Extension
- Wonderful Whims
- Better BuildBuy
- TOOL Mod
Players should:
- download updated versions
- remove outdated files
- check creator Discord servers
- avoid old repost websites
Even one outdated script mod can completely lock Sims 4 during loading.
Broken CC Can Also Cause Infinite Loading Screens
It is not just script mods causing problems.
Broken custom content after the latest Sims 4 update may also trigger:
- frozen loading screens
- infinite world loading
- CAS crashes
- black screens
The new Create-A-Sim base layer systems introduced in the patch appear to be conflicting with certain:
- clothing CC

Players with massive CC folders may need to use the:
- 50/50 method
- Better Exceptions
- Sims 4 Tray Importer
to identify broken files.

How to Fix Infinite Loading Screens in Sims 4: test a specific save
For a problem limited to one household, create a backup of its save files before trying anything else. In the game’s Load Game menu, check whether Recover Save offers an earlier version, and test it without overwriting the current file. Do not remove every save at once. If a new save loads normally with Mods disabled, isolate mod files in batches before returning to the original household.
How to Fix Infinite Loading Screens in Sims 4 when the main menu never appears: test with the entire user folder temporarily renamed to The Sims 4 Backup, then launch to generate a fresh folder. If that works, restore the original data cautiously; if it fails, move on to launcher repair and EA app cache clearing. Keep all backups until the cause is confirmed.
