Windows [HELP] Game crashes when starting new day. Error log included.

[Joosh727]

Game crashes right after going to sleep, but before saving.

Found a similar issue on the forum and tried the fix. Verified game files on Steam with no luck. Rolled back to the save of the previous day which did fix the issue for that in game day, but after a few more in game days the issue returned.

Message: Error on new day:
