Sims 4 Not Opening through EA App

Anaqins​  You can move your saves and mods from the old Sims 4 folder to the new one.  Move your mods first, testing them in batches or using the 50/50 method I linked earlier.  The point is to find out first if there are any mods or cc items that are preventing the game from working.

Once you've sorted through the contents of your Mods folder, you can simply transfer the contents of saves, Tray (saved households and builds), plus Screenshots and Recorded Videos if you care about those. The rest will be recreated as necessary.
