I always have last exceptions in my sims 4 folder, usually 2 or 3. I make sure to delete them before restarting my game. Is this the same for everyone? I am a totally vanilla player.
I wouldn't say last exceptions are normal - they generally say when there is something not right in the game. If you are using mods, you generally don't need to worry about this unless something doesn't work. But I would not expect last exceptions to occur if you don't use any mods or cc. Have you tried to repair your game via Origin? Perhaps it will help you get rid of the last exceptions.
Hope I helped.
