Sims 4 Error CE-34878-0 On PS4?

Hello

I get the same problems and try the solutions, but it didn't work. It seem I found a way for me, I hope it can help the other ones.

1. With this step, I could play a few time (15-30 minutes) without crash, so you can try it to make my solution more easily. Copy your library on a USB drive or in the cloud, and delete it. Delete the autosave too (I know, it will reappear when you play, but it seems to crash less quickly like this)

2. In the game, check the inventories of your sims and get ride of the 99+ stack. You can keep somes, but the more the better. For rare or hard to get item, you can drop some on the ground, sell the stack, and take back what you dropped (Or plant it, for me, the stack were mainly fruits and vegetables). If you have a lot of sims, or a lot of 99+ stacks, don't hesitate to save several times. When it's finished, don't forget to save.

3. There is a chance that the game crashes if you continue playing after that. Switch off your PS4, go eat a snack or in the toilette, and come back to play.

4. Eat your vegetables and save often. I tried this yesterday to lag less and play more before the crash, but I could play a whole hour without crash, and I stop because I had to (work) for the first time in monthes. If it works for you, avoid to recreate 99+ stacks after a few days, and don't forget to save, since a crash can alway occurs

5. Don't forget to load back your library, if you deleted it.

I hope it will work for you (and it will continue to for me^^)
