Time/Sim freezes while environment still moves

Hi! I have never posted in a forum like this before, so please understand I have exhausted nearly every available option before posting. About a week ago, my game randomly froze during playing, and I had to ctrl+alt+del and open task manager to exit, as the in-game time had stopped and I couldn't select anything in game or in the UI.

Upon reloading the game from my last save, it shortly did the same thing, at the same in-game time of 6:33. Over the course of the past week I have repaired my game files, updated and checked all of my mods, restored previous save states from days before the issue, hunted to find an exception file (to no avail), and scrolled through countless forum posts. At first I thought it may be the Father Winter freezing issue since it was Winterfest in game the day the bug started, but the game continued to freeze at 6:33 when I loaded days previous.

My other saved games load fine and the clock passes right through 6:33 without issue, it appears to just be this one game. So, while it's not the end of the world, I mostly just miss my main sim </3 she was pregnant and had level 10 handiness and cooking. Help please !!
