Re: Sims game not opening after update Jan 2025
@hihiyoolacky You can start moving your content from the old Sims 4 folder to the new one. Start with your mods and custom content, if you have any, and test the files to see whether any of them are causing the problem. If you have a lot of items to go through, the 50/50 method can make the process much more efficient:

Once you've sorted through your mods and cc, you can transfer the contents of the saves and Tray (saved households and builds) folders, plus Screenshots and Recorded Videos if you care about those. The rest can be discarded.
