Hello @Ghawor, please note that the singleplayer client has trouble handling the same load as the online client, especially on console.
When dealing with crashes related to the system being under too much stress we advise you to reduce the number of light sources to a minimum, as well as keeping the number of NPCs and placeables in check, if possible, as the crashes are in many cases caused by high amounts of placeables and lights in the same area.
Additionally, could you please provide a few screenshots of your base and the surrounding area, and let us know which PS4 model you’re using, the type of disk your game is installed to (HDD/SSD) and whether you have similar performance issues while playing online?
