My sims 3 64 Bit is stuck on the loading screen to my saved game

So I have a MacBook pro 13 inch 2020, four thunderbolt 3 ports

processor 2Ghz Quad-Core Intel Core i5

Memory 16 GB 3733 MHz LPDDR4X

Graphics Intel Iris Plus Graphics 1536 MB

I'm trying to get back into my saved game that I've had for a while now. In my saved game I have an elder sim, an adult sim who's pregnant, a young adult sim and a toddler.  We also have a dog that is blacked out, like my dog aged up to an elder and he turned completely black.

A lot of times I can't get past the loading screen to the saved game, other times it will crash after either a minute of playing or an hour. I'm not sure what to do at this point it's quite frustrating.

@classicacosta  Try loading the save in a clean user folder.  Move your entire Sims 3 folder out of Documents > Electronic Arts and onto your desktop, then open the launcher to create a new folder.  Inside the old folder, right-click on the Saves folder and Copy, then open the new Sims 3 folder and Paste.  Don't add any other content, at least not yet; just see whether the save loads.

The blacked out dog is probably caused by bad custom content, which should be clear from the results of this test as well.
