Unfortunately the save slots are at this level on PS5 because Baldur's Gate 3 has utterly monstrous savefile size. I have 76 saves on my PC right now and those alone take up 2.1 GB of space. A rough estimate of how much space is likely allotted for save slots on PS5 is around 1-1.5 GB. I didn't realize how bad it was until my computer was having issues saving because I had 26 GB of saves from a single playthrough.
