Error 34- Constant Corruption of Save Files

I play on Xbox and my save files keep getting corrupted, automatically deleted, and the message Error 34 keeps popping up. This has been going on for a little over a year now. I went through over 5 save files during this time. I thought that I had figured out the issue being I just cannot take photos in game with the camera or phone as I had seen a previous thread saying this and it seemed to have worked for a while or so I thought. I had seen another thread from one of the Community Simmers saying it’s because the xbox doesn’t have enough room to save this but this is the only game on my Xbox and it doesn’t even take up 15% of the storage? I tried deleting almost everything from my library and it hasn’t helped. It seems like this happens around new pack releases but I’m not sure. If anyone has a fix for this I would really appreciate it !
