Before you log out leave your character minimum for 12 minutes doing nothing. If your game goes into infinite loading screen and you forc3 close it at least you won’t loose progress.
Also turn off any type of crafting, smelting in your benches, it raises the risk for game freeze, infinite loading screen on log out too.
Sometimes waiting may go up from 12 up to 24,36 or even 48 minutes of waiting in order to save your progress. But that are some hardcore cases I had with Conan Exiles in Single Player.
Maybe try start playing on official Exiled Lands PVE server, you won’t be loosing progress due to infinite loading screen on log out. But there’s some issues with playing multiplayer too. Just be reading posts in PlayStation Bug Reports daily.
