Thanks for the log.
I'd check Xtardew.
The Sophia in that error has those 2 dots after the name. Might be a typo, or a way to copy the NPC.
SDV Expanded, and Xtardew are the only ones editing Sophia, and the farm event.
And, since you're crashing on a farm event; I'd definitely check Xtardew as mentioned above.
Maybe remove it temporarily, and see if it still crashes.
