Bug/Issue Game Crashes when saving only when farmhand goes to desert/skull cavern that day

When I'm hosting the game keeps crashing after we go to sleep at night just before saving, but after trying a couple times it only seems to be when the farmhand goes to the desert/skull cavern didn't isolate which was causing the issue, but saved a couple times trying other things and didn't seem to have an issue until she went to the desert to go into the skull cavern then it crashed when saving that night. Error log included below and I've checked the log for each time it's happened and it's identical. Attaching the save file in a zip and original error log. Help is appreciated my wife and I have been having a lot of fun with the co op and all she wants to do is go to the Skull Cavern.

Message: Operation is not valid due to the current state of the object.
