Save File Freezing because of background pregnancies

Hello! I have a Sims 4 generation save file that keeps freezing. I am certain because of the pregnancies/births in the background. This save file has a ton of families that are connected since I have been playing this family for a long time.  When I first start the game, the simology panel for the families shows up. Between 3-6 am a birth happens somewhere, and the game freezes. When I check the simology panel, nothing shows up anymore.  I do not know what to do to fix this issue. 

Steps I have tried, and still expiernce the issue:

• Removing all mods
• Playing with just MCCC
• Recovering save files
• Playing with two completely unrelated families in the save file, both with and without mods
• Repairing the game
• Cheating the time past 6 am
• Changing MCCC settings and turning off neighborhood stories
• Deleting cache files

I would really like a solution since this is my favorite save file. Please help!
