If your game is crashing after recently updating it please try the two most basic and fundamental steps to resolve it before posting:

Repair the game in EA App
Test a new clean game. Don't just cherry pick a few files and folders you think you should remove, such as just the Mods folder, or a few random Mods, or any old cache file, or a couple of screenshots, test a completely new, clean, vanilla game. Full instructions here - [INSTRUCTIONS] How to troubleshoot and test a broken game | EA Forums - 11864548

If your game successfully launches with a new Sims 4 folder you then need to figure out what is causing the crashing/failure to load. Again, instructions are in this link - [INSTRUCTIONS] How to troubleshoot and test a broken game | EA Forums - 11864548 . Only you can do that and it can take some time.

if the cause is Mods head over to the Mods forum for further help - The Sims 4 Mods & Custom Content | EA Forums
if the cause is one or more particular save files, upload them to a file sharing site and post the link here (tag me) or PM me and I can test in my game

If your game will not load after repairing it AND testing a completely clean Sims 4 folder please post here with the specs of your Mac. You can find these in Apple > About This Mac:

model, e.g. M4 MacBook Pro
year, e.g. 2024
macOS version, e.g. Sequoia 15.3.2 (yes, the FULL version is important, with all numbers)
memory, e.g. 64GB
storage available, e.g. 1.5 TB of 2TB. This info can be found in System Settings > General > About or More Info... in the About This Mac window.

Please also post a screenshot showing the contents of the new Sims 4 folder in Finder:

make sure the files are in list order in Finder with Dates and Size clearly visible.
make sure all files and folders in the TS4 folder are showing, don't cut off the screenshot
have the path bar clearly showing in the screenshot: with the Finder window open and selected click on View > Show Path Bar in the menu bar at the top of your desktop.
The screenshot should look something like this:
