Error code 123: 259a6556: 5e24aec7.

Please test your issue on a vanilla game

To verify on a vanilla game, move your mods folder to the desktop and delete the following files from your user folder.

-  localthumbcache
-  Any lastException Files
-  Any LastCrash files.

Test a backup of your save as you will loose all cc on the save and see if the same error occurs, then report back.

Hi allysonlelievre1​ 

did you get a chance to test this with no mods/cc ?

Same problem after the update. I wish they would just stop updating and screw up my game! 

It happened after updating the game. After selecting the "new game" option, I started over and created a new sim. I placed the sim somewhere, and when I tried to play the game, it gave me an error code. When I tried to play with any family, it gave me an error code every time. How can I solve this problem?
error code was written like this: 

The game failed to load. Error Code:

123:259a6556:5e24aec7. It is recommended that you relaunch the game.

Hi nevramirayz​ 

Do you have any LastException files in Documents\Electronic Arts\The Sims 4 ?

- Delete the ones you have
- Trigger the error again
- Check if new ones are created
- If that is the case, please copy/paste the content here. You can open the file with any text editor.

Deleting the file won't fix your issue. Posting the info is meant for troubleshooting.
