Do you remember if this log was from a time you crashed? It doesn't show any errors or the game closing unfortunately, so it's not obvious.
The save itself is probably fine, but lacking anything that jumps out, the simplest thing to do is try removing some mods and see if you still crash! In case it's cellar-related, I'd start with Seasonal Garden Farmhouse and Multiple Spouses. (I don't think either of those have any known issues like this, but at the very least it will rule out any interactions with other mods!)
If the obvious ones don't help, you can always rename the entire Mods folder (to anything but Mods) to confirm it does load without any mods, then add them back in batches until it crashes again. Isolating the mod in question is the first step to fixing it, if fix it we can :) (As long as you don't save there should be no lasting change to your farm, and even then you could roll back to last day.)
(Note that if you're married to a custom NPC, it's unlikely you'll be able to load the save if you remove the mod the NPC is from, so I'd save it for last.)
